318 cylinder head
,@David Eldridge, i don't see anything wrong with just doing a nice valve job to your original 318 stock heads and leave all as is. Stock cam and all.
Here are a set of thin head gaskets to use with your fresh valve job to help keep the compression up. Made for the 318s.
One recommendation is to port match your intake manifold to the 318 cyliner head ports so that you don't have a square edge there coming off your 4 barrel manifold.
Here is a Stock 1969 318 with a 4 barrel added to the stock 318 intake and stock cam and single original exhaust system. Ran out really nice, great performance and gas mileage.
318 4bbl / 727 trans / 2.94 rear gears, one of my favorite stock drive line setups.
