There is a Comp Cams lifter that has the guide bar moved from the block side of the lifter ear to the opposite side. I have heard this does away with most or all the the block grinding. It does not change any head mods though.
yes #8043-16 i think is the partnumber,my set dropped right in they are close to the block but does not touch enough clearance in my block that i feel safe!
on the isue with grinding the heads im not realy sure, since the guy who ported my heads asked me about what size pushrods i was going to use before i got the heads back so he might have clearanced them alitle for my 3/8" pushrods but they dont touch anywhere that i have noticed,and the pushrodholes are straight.
