FYI Felpro are the same as stock. The last time I checked stock Ford gaskets were made by felpro, cometic, and one other company I can't remember.
The most economical head gaskets come from the FRPP head changing kit.
I'm very curious as to where the 1500rwhp is coming from? It's incredibly difficult to get any motor past 1000rwhp imo. In fact many have had a hell of a time passing 800. Usually they get so fed up trying that they sell everything and buy a prius.
Just my opinion but far too many people with no experience throw out all kinds of bs.
I like the tty hardware because it's impossible to overtorque and cause stress, fractures, or both. I think the tty bolts Ford uses are more expensive than using a stud would be but it provides a greater degree of reliability due to the exacting torque application. We almost never hear of blown head gaskets in modern motors and I think this is part of the reason along with better machining.
It's not a popular opinion but the results speak for themselves. I've been of the opinion that if you need studs then you are also going to need lockwire o rings and soft copper gaskets.
I've never done more than fill, run with the cap off, refill and cap when it comes to coolant systems. Been doing it that way for about 40 years with a variety of motors from tractors to cars, never had an issue and can't really see where anyone would need a machine for home use. Maybe if I ever had an issue I'd think differently.
I'm still trying to wrap my head around how an air pocket would break a block. I'd think that the cap would blow off way before a block would break if pressure was that great.
Bruce,
This was another post of your's that stood out to me in a positive way.
(No real surprise actually)
When my B-302 was originally built at Brenspeed by Kent Nine they used the TTY Ford hardware.
That was way back in Jan 06-2011.
Years later Brenspeed did some major changes to the engine including the Ford Racing Heads, Roush, etc.
So once again I asked Brent to go with the ARP head-bolts etc.
I had also ask Brent to do that the 1st time when Kent built it Jan 2011.
Honestly I could not recall what the heck Brent told me as to why they did not go with the ARP versus the Ford TTY.
My memory is not that good after 4-plus yrs. had passed so I brought it up again.
This time I listened very closely to what he had to say on why they don't use ARP.
This is not going to be exact but in general with my own words.
Terry we don't use the ARP because they offer No-Ability to stretch between the block & heads.
It's much better to have to simply reinstall a new set of Head gaskets than to have a broken block or heads.
That's not exact and sure is not Brent's exact verbage but it does say in general what the reason was they don't use ARP bolts.
So I told Brent do it the way you see fit.
I have read so much on the internet about people saying don't use Ford TTY use only ARP that's why I asked you again.
I think your right on those 1,000 & 1,500 RWHP cars.
Especially when you read they are street cars.
Mine right now at the rear wheel is in the 740 to 750 range at the rear wheels.
I'll just say this the best way I can as a layman.
I'm not in anyway a tech and can't built crap.
But I do think the overall engine in my Bullitt is what I think is pretty bad ass.
It to me has a lot of high tech components and it works very well.
But it is a heck of a very long ways from even an 800 RWHP car.
(I'm not referring to drag cars only)
I'm referring to cars you get in, start up, warm up, and drive anywhere in the USA with no worries.
So when I have read the post here by Bruce that IMO does know what the heck he is talking about I agree.
Also I'll add this regarding my Mustang it has right now 53,000 miles on it.
It is a 2008 Bullitt Mustang that has been raced by Brenspeed and many-many-times by me.
As I said above the built B-302 SC engine went in way back in Jan 2011.
With all the miles and racing on this engine there has not been a blown head gasket or anything like that happening to it.
The only thing that has happened to it was the stock cam follower coming loose.
That was with me pulling out of a local business onto the street with basically it idling so I didn't rub anything under the car.
I have not posted anything as I have read numerous threads/posts on all the different problems members have had with building or after they have built their engines.
I just do-not really get it to be honest what and why people have all the problems they do with very high dollar builds.
I have kept reading and hoping I might eventually catch on to what is really the difference in mine and these other builds.
In fact many have had a hell of a time passing 800. Usually they get so fed up trying that they sell everything and buy a Prius.
Bruce I have seen that exact same thing take place right here on this site.
The guy (Joe Roberts) from I think Montgomery, AL. that had the Yellow GT Mustang.
Brenspeed did the B-302 and Joe wanted some wild RWHP and it fell short.
So he basically then redid the complete engine and went with a huge supercharger.
http://www.s197forum.com/forum/showthread.php?t=99453&highlight=joe+roberts
He finally got to 888.4 RWHP & 879.7 Torque.
What did he do after spending all that money and time ???
Put it up for sell and finally some dealer as I recall bought it for pennies on the dollar.
I went and met Joe in person and saw that Mustang also.
Here is what Joe told me when we were discussing our two Mustangs.
Terry mine is now nothing but a hobby car and I don't trust it to even drive it locally anymore.
Soon after that I saw on here he put it up for sell.
So Bruce I know exactly what you are saying and it is true.
Brent and I talking to one another has told me that exact same thing years ago about guys going crazy with their builds.
He basically said, Terry they don't know when to stop and the next thing they go so far the Mustang they have is no longer even drivable.
Then they get disillusioned and put it up for sell.
I think with my limited technical knowledge and just plain Ole-Common-Sense people do go overboard.
They read on the internet and think man I need this and that and I better do this and that when in reality it's just not true.
Here is a picture of the 1st Brenspeed built B-302 SC engine back in Jan 2011.
Look at this picture closely that me and Kent are holding up and you can see the date.
