small block heads, 4027596 casting # any good??

OH, I alsomost forgot, skip the polishing andwhat is your combo?
IMO, stock 1.88 valves can go along way. So if new valves are not in the budget yet, keep'em if there good. If not or money comes in, you could get larger valves.
pretty much what i said. no? and i added a link for him about porting later 360 LA heads. yah.. guess i did ruin the post. my appologies.
