What head Gaskets to use when boosting above 25 psi?
I now have:
5.3 LM7 iron block
Pistons and Rods Forged Summit Racing
Heads 317
BTR stage 2 camshaft KIT
Turbo BW s475 T6
LS9 Head Gaskets
ARP Head Studs
intake summit racing Fabricated Intake Manifolds
compression ratio 9.4, gus pump 93, injection methanol/water, boost 24 psi and 17 degree
All this gives me 800 HP
Now I want to make a new assembly:
ARP Head Studs 1/2 Viper
K1 Technologies Forged Crankshafts
Ported head 317 and installation Manley Race Series Stainless Steel Valves
But I can't decide which head Gaskets to use to raise the boost to 29-30 psi and make 1000 hp. My car is for street driving.
At the moment my Mustang is the fastest in Russia with 1/4 9.7 sec.

If you really are in Russia, would love to see some photos from the car scene over there, love hearing from diff parts of the world what their doing with cars. I remember a guy over there with a chevelle.

Now that's cool, didnt realize they had a track. Has to be hard to get parts, but looks like you guys are doing good. When we have Drag Week over here, we get guys from several countries come over, but Covid 19 is affecting travel. Really interesting to talk to them.
Thanks

Spare parts are never available, you have to order everything from summitracing.
Good point on the gasket width, so I grabbed some heads.
862 head, comes on 5.3's, chamber width across the valves is roughly 3.768 or 91.3 MM
317 head is 3.910+, or 100 MM-I have some 799's, prob dig them out, but prob close to the 862's.

I remeasured the 317 head again, its more like 3.935 to 3.940, so about the size of that gasket. I had a set of factory 6.0 gaskets, they meas 4.040, for the 4" bore block.

I understand, thank you for your help. So I will focus on these gaskets.
If you can, then another question.
I use Chevrolet Performance 12499225-Chevrolet Performance Hydraulic Roller Lifters, Is this the right choice for my purposes?
