Thanks for clearing that up Daytona and Rapid. Im still learning. Although, if the block wasnt decked, then wouldnt that increase the piston to head distance, creating detonation and bad squish, but also lower CR? Not trying to argue, just learning.
Stanton, I dont want to go the NOS route, but its a good idea. I would like to achieve 500 HP, but it doesnt need to be there.
I am surprised to hear that the source heads dont flow well enough though. They seem to match up, number wise, to Eddys which Ive seen on plenty of 500+ hp builds.
