Help with cam numbers for Supercharger

Hello everyone ,
I’m in the process to bolt on my supercharger to my gen 1 but I’d like to degree the cams to get the most out of the blower. It’s a Gen 1 with the Gen 3 intake kit cam and stock Gen 1 exhaust cam. Currently they are set at 110/103 which I didn’t like when compared to the Gen 1 kit cam dialed in at 107/104. The ecu is flashed to 14,200 and the motor is completely built so she should hold together. I was on the forum a lot years ago under Inginekilla but I lost my password so I opened a new account . Any insight will be greatly appreciated.... needless to say I’m really looking forward to getting my Gen1 back on the road since she has been sitting for 4 years waiting for me to bolt it all up , since then I have gotten 650cc injectors to support the fuel needed at 8ish psi. Thanks guys , I’ll post pics when it’s all said and done 👍

This is gonna be interesting, I'm not sure what numbers work with the stock G1 ex cam but I'm sure somebody will be along shortly. 14200 rpm ? Are you using the green valve springs all round, iv had good success using those on G3 race cams, and more aggressive profiles but i have never asked more than 14000 of them and I only use new springs on builds, those G1 springs are 14 years old now.....just a thought mate.

Depending on pistons and compression, dial the cranking compression to about 160-170 psi

no need to that far in rpm to get power...
I would go to 13800

I would ad bit overlap over stock in the cams.

I followed the spec for the H2, 170psi-ish, with 8.8:1 compression

Did a supercharged Busa, with Woosner 9:1 with 160psi and it ran great.

Had a friend running 13:1 and running a turbo, had 220psi, he spun 1 rod bearing twice before consulting with me about his issue. After the redegree, he ran the motor to a personal best at the strip(8.10s)

Its a delicate balance of power.

Adding a thicker head gasket because your head has been decked is the wrong way to go about it, especially on the boosted engine, you're making the squish clearance bigger, which will make the engine more likely to ping than the engine with higher static compression and tighter squish clearance.

Even if I’m running e85 you think it’s going to be prone to detonation do to me adding a thicker head gasket ?
