FOR BRENT: Do you have my camshaft specs when you built the engine ? I don't have any specs or camshaft reference.

Let's hope you didn't understand exactly what the "racing engine specialist" said. It's either that or he didn't tell you the whole/correct story. Your "heads" don't dictate maximum lift. The installed valve springs accomplish that. Edelbrock was referring to the max lift on their installed valve springs. The valve springs are matched to the cam. My 482" aluminum Pond side-oiler has the FE Performer RPM heads (CNC'd) and I'm running a .650" lift cam. 20K miles in 12 years and zero
oil consumption or valve/chamber coking. The guides are as new.
