What pushrods?

My Magnum'd LA engine(318) required a 7.350 Push rods. I was using the same head gasket as you, .024-.028 compressed. I bought the 7.650 rods but they were way too long. There seems to be such varying deck heights on these LAs that you might be better off getting a adjustable to measure you length. Pushrods, even custom length are reasonably priced.
