302 30/30 valve adjustment
For my first post on this forum I would like to ask about adjusting the valve lash on my 68 302. I have rebuilt the engine and now have it back in the car and running. While the engine was still on the engine stand I adjusted the valves using the John Hinckley and Duke Williams method which you can find on the CRG Research Group website. (start on TDC and turn the engine 90 degrees 7 times adjusting 2 valves at each 90 degree position at .027). Now that the engine is running and somewhat broke in (there are a couple valves that are a little noisy) I am going to adjust the valves again. The cam I installed is the Federal Mogul Speed Pro 30/30 grind part # 53059 12002 and the rocker arms I used are the Comp Cam 1.5 ratio roller tip stamped steel rockers.
Here is my question......Is the Speed Pro 30/30 cam Identical to the original cam where this adjustment method would still work, and are the Comp Cam rockers different in some way that this adjustment method would still work? I think the method is fine but would it change the .027 clearance?
Thanks in advance to everyone who replies.
