Once you raise the compression, you are going to seriously assess your fuel ... with e85 the obvious solution.
JUN cams and retaining VVEL will not cut the mustard - you will get close, but not exceed 400rwhp.
The other issue you will have is the ECU - the OEM ECU is not going to do the job.

I eventually plan on purchasing a dry sump to cover the oiling problem. I've been debating on the Hr head conversion or just sticking it out the VVEl heads. I just want to know what is the big difference in the Hr Heads Vs the VVel heads as far reaching the mythical 400 whp. Lack of research? too much of a pain in the *** to deal with? Hr easier to work wit? VVel just plain out to complicated?
