of the 3, brisk has had the most issues, i personally would not use them
So autolite htos are the way to go then?
Also what is a good gap?

I've used both the autolites and Ford m-12405-3v0 which I think are essentially the same.
I always have to .032" also buy the happing tool. It works well.
Yes I have the earlier heads from 08 so I’m not sure which to go with

That is what I’m hearing after more research. If you had to choose between the two, which would you choose and why? How often do you check or change yours? I personally can not find the ford ones.

I think they are the same. So either is fine. I change them every other winter. That's probably more than needed. But I used to race a lot. So that seems like a long time to me.
Hey OP,
I installed the KB Stage 1 offered by Carroll Shelby earlier this year. Didn't have to change or modify anything on my 2007.
As far as plugs go, KB recommends the 1 temp colder plugs by Brisk.
I have attached a supplement article from KB that was provided in my kit. There is a part number and phone number for anyone 2008. You could also call KB and ask for Rick. I spent a lot of time on the phone with Rick and he is a good source of knowledge. I have never had any issues contacting KB by phone or e-mail.
I used Brisk PT# 3VR14. These are rated for HP range of 450 to 599 and work very well for me.
KB recommends the 3VR17, which have an HP range of up to 450. If you plan to exceed that in time the 14's work just fine. However with yours being an 08 I do believe plugs changed so call Brisk before taking my word on it.
I have about 3k miles on it since install. Blast to drive!
As far as "screw whine" these kits are very quiet out of the box. Even KB states this if you ask them. You could do a sound tube mod but know you'll get additional induction hiss through this tub. So if you're not constantly in boost and above 3k rpms mashing on the throttle the pay off may not be worth it. I did this and immediately bought another intake tube from KB as I couldn't stand the Induction noises during normal driving. Granted hearing the Whine did provide some satisfaction.
Hope this info helps.
Cheers,

As long as you apply nickel anti-seize to the electrode shield barrels? the HT0 plugs will not separate. Also as mentioned in a previous post, you should change the plugs every 2-3 years when running a S/C application anyhow, due to the increased cylinder pressure. If you change out the plugs as recommended? you'll avoid the potential risk of having carbon build up around the electrode shields, to begin with anyhow. Therefore, if in your opinion the HT0's are better plugs over the Brisk's? then by all means, go with the HT0 plugs.
