CompCams, PT# 7901-1 adjustable push rod for checking correct geomerty and a 12" set of calibers.
Don't know what heads you have, but you would not believe the problems i just went thru getting the correct pushrods for a hydraulic roller conversion for a customer. He had Procomp heads on a b/blk chevy and it took 8 stock, and 8 .250 short pushrods to get the correct geometry. I had ordered some of the parts for him, and he had absolutly no knowledge about correct rocker geomerty. The only thing he saw was that some of the rockers was hitting the guide plate with the valve closed. Some people should absolutely not build their own engines, such as the guy i'm talking about.
