ProComp/Speedmaster aluminum heads
I remember on this 318 for my wife I had some 360 heads from a core motor that I took apart and sent down to a shop and had .060 milled off.. I had the newer 188 intake valves from when I had my 202's put in my current heads. I took some lapping compound and put it on the edge of the valve and the seat and put a little piece of rubber hose over the backside with my drill and pushed a drill bit in the other side of the hose. I slowly buzzed it back and forth until the grinding sound went away which only took about 10 or 15 seconds... Cleaned everything up real well put new seals and lubricated everything real well with whatever green goo assembly Lube that I had and put everything back together and they seem to work great..
