Head Milling ?'s
Head Milling ?'s Hey guys
I think Im going to mill my 317 heads .030 on my LQ4 with a stock metal gasket. Now will I need a short push rod since the head is a little shorter or will my stock ones be fine?

Yes you will need shorter pushrods if cam is unchanged. So LQ4 with stock cam and milled heads will need shorter prods.
But if you have an aftermarket cam stock length may be allright depending on lobes and lift of cam.
Bottom line measure.
