Not a problem...lol..I'm still waiting to try some of the valve size ideas on the bench I have access to. Just need the $$ for the valve jobs and parts on the test heads. I have a set of 915s, and a set of 302s I'll be testing, from original as removed from the engine, to finished, larger valves and what I would call "stage 2" porting. I'll post it all when I do it, but it may be a while. I also need to buy the larger bore tubes..the bench came from a motorcycle guy, and they are all tiny for what I'm doing...lol What size bore were you testing with anyway?.
