What wall thicknesses are you running and what kind of spring pressure are you looking at? What brand of pushrods do you have?
I am looking at 3/8 .120 wall now. I am waiting till I cut my heads .040 before I order pushrods want to verify the length one more time before I order them.

I wish I could give you more info but that was over three years ago. I’ll try to look for the paperwork on my messy bench tomorrow. I know they were tapered 7/16 and expensive. I’m going to bet Trend.
