this is a marine application with a somewhat restrictive two to four plate which i would like to put a holley 600. rpm wise cruising rpm is around 3000 max 4000 or so also i plan on using a mallory unilite or equilivent... heads will be stock rebuilt, comp is stock. i did notice after checking the numbers that the block is a 292 but the head appears to be a 250. good or bad? dave
