Anyone use the RHS 360cc Pro Action or 376cc Pro Elite CNC Pro Heads? Are the CNC version worth the money? I'm building a pump gas 632 and was thinking of using one of those or the Trick Flow 360cc? Any thoughts??
I haven't seen a set of TF360's, but I really like the TF's products I have seen. Good QC, good quality parts and good performance. I had a lot of issues with the last set of RHS 320's I did...had to send them back for a replacement set. If you buy an assembled set, have your machine shop disassemble them and check seat runout and guide clearance, and compare the two heads to make sure they're the same. The ones I returned had .080" difference in ex. seat height from one head to the other, and the guide clearances were unacceptable. The TF stuff I've seen was all right on. I don't have any experience with Pro Action. I tend to avoid any cyl head with a name that starts with "Pro...".
