LS3 - thread pitch for holes on front/back of head? On an LS3 525 crate engine (L92 heads I think) does anybody know what thread pitch the holes are on the front and back of the heads (where you bolt accessories, etc...) to?
3/8 course thread fits but I get some resistance after several turns .... I don't have any metric bolts to test with.
