so im planning on doing an h2b build and i will be using skunk2 pro1's, full valvetrain ect. Now i will be using a stock block. Will i have enough compression to get the most of of the pro 1's? If not i was thinking maybe a thinner head gasket could help a little bit. And this will all be on 93 octane.

 

evidently you are the tuner you tell us.

ill say if you are running a usdm motor you will not have enough compression to utalize those cams to their fullest potential. if you have plans of raising the compression id say go for it. when i talked to skunk2 they told me that if i didnt get the compression closer to 11 i should take it a step down and get the s2s2's. im running the jdm h22 btw.

 

i will be using an jdm engine

 

The more CR the better. The Pro1's have made good power on stock block H22's but would obviously make more with higher CR.

 

While I will agree that they would like more compression, they will be fine on the stock jdm block.

There are quite a few dynos of the pro1s on stock blocks laying around. . .

FWIW- I will be running pro1s on my stock block as well

 

get some flat valves (or not) and get the pro 1's. the 10.6 will be good enough
