kvansic162 Posted August 16, 2008 Share Posted August 16, 2008 I want to make sure a p90 head will work on my 77 (used to have n47 head) block. I noticed 2 water jackets will be blocked by the head gasket. Will this cause a problem? Do I need to do anything special where those holes are?

kvansic162 Posted August 16, 2008 Author Share Posted August 16, 2008 wouldn't I want to use a 77 head gasket to block the holes . Isn't the cooling holes on the n42 block different than the p90 head? Quote Link to comment Share on other sites More sharing options...

rick240zed Posted May 1, 2014 Share Posted May 1, 2014 The advice given in this thread is contrary to what I have read in other threads. Could someone please confirm: - if you have mismatched head and block, should the head gasket match the head (as indicated in this thread), or the block (as indicated) in other threads Quote Link to comment Share on other sites More sharing options...
steve260z Posted May 1, 2014 Share Posted May 1, 2014 (edited) It matches the head. Edited May 1, 2014 by steve260z Quote Link to comment Share on other sites More sharing options...
