Some pre machine shop work.
I use orange spray paint with a stock felpro gasket aligned and taped down to gasket match. I also open or thin and shape... the 'push rod pinch' later in the game as needed. The picture with the one short turn done is something I did for fun, to see what it does with the 1.88 stock vj while semi heavily ported.. and short mildly ,tee hee.
