After you lap the valves in. Take the intakes to a machine shop & have them do a 30 degree back-cut close the the outer lapin line.Maholmes76":2aqfpdcc said:Was lapping the valves today and noticed small Annular groves as I did them. I am using the lapping hand tool. And permatex valve grinding compound. Is this going to be ok. Not sure this is the first time I have lapped valves
A 30 Degrees back-cut will gain you 10 HP.Maholmes76":2mpk7npa said:Chad
Sorry for the lack of response. Not real good at this forum stuff. I have been taking your advise. And getting my ducks in a row. Can’t find a way to respond to just you if you even can. Still learning.
