Speedmaster heads part 2. Plus intake work
Last couple of pictures and due to lack of interest my last post on this. I may start another post on intake porting at a later date with flow numbers. Spark plugs holes have been modified. Other than that very little chamber work. They are going on a stock 1973 (340) so compression is low to start with.
