I talked it over with Hughes. They said on a motor like this it isnt worth the EQ heads, he admitted that was him just being frugal and assuming the stock heads arent cracked. Although according to the numbers on their site with just the replacement version of EQ, the stock magnums outflow them to .300 and they are barely better at .400. The stock magnum cam is like 180 or 178 @ .050 and its on a 116. With the smaller cam I wont need to touch the computer, and Hughes figures if I do a throttle body, headers, exhaust, cam, K&N intake, I'll be right around +45-55 hp and torque. I may pull the stock heads and have them freshened, just cause its 10 more bolts from where I'll be, why not throw some hard seats in them and be done with it.
