Hi all!
I'm beginning a rebuild on a casting #61010 2F block, serial 05331 presumably from '75. It has flat-top pistons that I would have to assume were put in by PO, most likely all going to be replaced...
Heres the question. In the purchase of this block (and 2 others) I was given 2 cylinder heads. One of which casting 61030, other 61031 and from what I can read NEITHER of them belong on a block with flat top pistons. However I can definitely tell that the 61030 was on this block previously.
Should I put in the effort to find a closed chamber head? (61010 or 61040 I think?) Assuming that the head(s) I have are in rebuildable state, should I just find some domed pistons and go that route? I understand they're pretty hard to find.
Thanks
