Save yourself a lot of headache & heartache, pick up Rocky Rotella’s how to rebuild a Pontiac book in the very least. I know from your previous threads you like to over analyze these things but at least arm yourself with a good foundation whether you do the build yourself or work with a machine shop. Rocky’s book is required reading for anyone looking to build or pay someone to build a Pontiac motor IMO.
