So is this essentially the same as paying for a stage 2/stage 3 porting job from a speed shop?

Stage 3 plus custom hand porting. He went way beyond my Foxlake porting.

I can agree with that. I have a set of Fox Lake heads here.

Any thought on the change in combustion chamber size and what affect that will have on compression, just a thought.

NA it's a big deal, but not as critical with a supercharger.

I CCed my heads after the gutting/porting. Then I milled them till they came back down to 48CC.

Good work! They look great. Where did you learn to do that kind of work? I have done some very light two stroke porting work but I had a template and reference pictures....you are making me want to pick up a set of used heads to play with. Are you using any kind of template or guide?

Thanks, I used to do a LOT of porting work back in the 90's when we we're running the fox body cars, we used to run f150 truck intakes with a custom dual throttle body inlet. This required a ton of welding and porting to redo the intake runners. I used to do this work in exchange for car parts lol. In short, I have a lot of seat time at the porting bench. The only template I used was my exhaust gaskets and intake o-rings.

There isn't much change in my combustion chambers, just unshrouded the intake valves, the rest is pretty much OEM just sand paper rolled smooth.

Finished at last! 2.5 more hours tonight, for a total of about 11 hours for the right head, again the left took longer so I would estimate a total of 23-24 hours, I think it will be worth it though.







My new Manley 35mm ss intake valves arrived today. These are single groove style locks, supposedly much stronger than OEM triple groove.




Now back to block prep, I ordered an 11mm x 1.5 bottom tap that finally came in, I welded an extension to it so it can reach the bottom of the head stud threads. I have about half of the holes that need to be tapped to allow the new studs to screw in completely by hand.

Those heads!! Where do i send mine to and how much! And also going to text u today or tomorrow! if u dont hear from me by sunday text me!

LOL on the heads, no thanks I had more than enough fun doing mine. Okay sounds good on the text..

Here's the bottom tap with the extension welded onto it. Problem is it apparently has the wrong thread tolerance since I have one hole that won't tap out, I can run the tap down to the bottom with my fingers but the stupid stud wont go! (it goes fine in other holes, and other studs won't go in this last hole) My luck strikes again, twice even since I found one of my brand new ARP 2000 studs is defective! Argh! One of the threads about .250 from the bottom is kind of crushed / deformed. This is the type of stupid shit that only happens to me! Now I need another new stud and another new tap, and another extension.



The good news is from the best I can tell the OEM intake o-rings will fit just right, if I went any bigger there would be an issue though. Travis there's your roll bar in the background lol





The next issue is I found that now my FRPP intake is a restriction. It used to have larger ports than my heads but now it's the other way around. I'm considering removing some material around the o-rings but IDK, I would just get a sniper intake if it wasn't such a POS. Maybe the new bolt together version will be good, it's supposedly coming out in the next month or so. Or if anyone has a JPC intake laying around they want to sell feel free to let me know (I know that would be like winning the lottery)

There is a little bit of material that can be removed..hmm decisions

 

[roberts]

Yea I see it back there. Just sell me the heads and I'll send u mine in part trade lol. Just bare heads is fine lol

After mocking up the intake several times and marking the o-ring outlines with oil, I confirmed they will work, and I decided not to mess with the FRPP intake. Obviously its only plastic so I don't want to weaken it since I'll be pumping 20+ psi through it.

After alternating the tap and stud in and out of the hole about 150 times I finally got it to an acceptable looseness, really weird that I had such a hard time with it but nonetheless it's finally okay.

Also decided it's probably time for new lash adjusters and followers for this motor, since my old set has been in three motors.


Pretty much just waiting on my pistons to arrive now, which should happen next week, then everything goes to the machine shop.

Did you find out what was causing the problem with taping that hole? Just dirt, alum, factory defect.

No, not really. It's extremely bizarre. I just ran the tap and stud into it about 100 times and it finally loosened up enough to be acceptable. It's still tight at the bottom, but only finger tight 2-3 turns out which is where I have it during assembly.

Stock is closer to 50cc correct?

50 or 51 I cannot remember right now

 

[Boone]

49.77cc is the combustion chamber volume for stock 3V heads IIR. CR was 9.8:1.

I learned something else really crazy, when removing my old pistons from the rods I found all 8 were seized up inside the piston pin bores to where I had to tap them out with a mallet and plastic driver. The rod bearing / bushing was good but both sides on all 8 pistons were seized pretty good. I then measured them and found all the pins are bent! Bent like an hour glass! WTF! Those pins were the standard grade Manley that came with my previous set of pistons, I didn't think the upgraded pins were necessary, WRONG!!! Well it's a damn good thing my new pins are made of H13 tool steel and are .200 thick.

Also I called ARP yesterday re the new stud I received with defective threads, I gave them the info on the box and they said I would have a replacement stud today, I was thinking yeah right, they're in California and I'm in Florida, which usually takes a week, but I was wrong about that too, in a good way, when I received the replacement stud today, literally less than 24 hours after I called them, now that's great service IMO.

 

[travelers]

It looks like everything has to be up graded when going to high boost. Good idea on the tool steel pins. Wow that's a lot of things going south. I think, at least the guys that are reading your posts are learning a few valuable tips.

That's some really good service from ARP

Yea I dont forsee going all out like you, but I figured the thicker wall wrist pins was worth it, just 1 more thing thats stronger, and it didnt cost that much to upgrade
