10.78:1 compression, 16 psi at the very top end, cam is retarded to decrease the dynamic compression ratio and clear pistons. I'm going to be working the heads to reduce that comp ratio soon also.

dyno'd 600 last time it was on there.

I've heard of people pulling this off (and 800-1000 whp) with stock head gaskets, is that realistic? Mine stock ones failed, but I believe that wasn't a byproduct of the gasket and was a flatness issue.

How do OEMs compare to the Fel-Pros?
