Tech Inspector1- I have followed your recommendations on the 327 build with the above parts from your post. I purchased Comp Cams 1.6 roller rockers to go with the Edelbrock Performer RPM heads. My pushrods came out of a low mile 383 and are Comp Cam 7993- 7.900 .080 They are too long because I can't even start a thread on most of them. Do you have enough info with what I have provided to recommend the correct pushrod?
