Manley Pushrods 25339-8

You know that’s for 8 right. If I’m going to spend that much money I’m getting custom pushrods. Also on many of these heads 3/8 pushrods will require clearancing. Especially if you start playing around with rocker ratios
Yes I am aware that's for 8. I am running the Indy 360-2 heads and indeed we are doing some clearance work....
Are they solid ? or oil through type?
