I am installing a set of trick flow heads on my 94 cobra and i was wondering if the fms rockers can be drilled out to 7/16" so they can fit on the rocker stud of the tfs heads.
just buy new one or trade yours for a good used set. thatt will save alot of time and head ache. the rockers are precise to the exact fit and if you drill on them it may throw off some precise mesaurment
