Have you ever tried your hand at a set of Hughes engines big mouth heads with the 2.08 valves , wondering if they left anymore flow with hand finishing , thanks
Thinking about putting a little helper on a low compression 340 I have , what experience does anyone have with this and which one is better do you think, thanks
laying them side by side with a 340 rod and measuring it they look to be identical, but I’m not an expert either , can’t find any other markings on them
I have a similar 416 and ran back to back test on Dyno with stepped tti to 1 7/8 tti , and the bigger primary’s are diffinetely worth it whether there hedman , hooker, tti
