I've seen a lot on here do it and some come back whining about how noisy their valve train is. I promise you that you can find my advice and a sctna handful of others advising against it, yet "us few" got argued into oblivion by those "who know better". All I know is, I love the way the Crane Fireball runs and sounds in the Ford 400 in Gladys. LOL Old school goodness at its best.
