Anybody recall the multiplier in the formula to get to the amount you need to take off the intake side of the head to make things sit square? I know John posted it a while back but couldn't find it doing a search. Only taking off 0.020 on unposted G heads so I might be ok without doing the intake side.

As I understand it, milling the intake side for a 0.020 head side cut isn't needed. And just for further info, our moderator Ted, does not recommend milling unposted ECZ- G heads more than 0.025"

The multiplier is 1.4. However, as Paul said, it is not necessary if only milling .020.

Didn't think I needed to do the intake side but wanted the multiplier just in case. Thanks

Just out of curiosity, how does the multiplier work?
Thanks.

Mark, whatever you mill off the head surface, you mill 1.4 times that amount off the intake surface. For instance, if you take .050 off the head surface, take .070 off the intake surface. If you also deck the block, you would need to add the amount taken off the block to the amount taken off the head, and multiply the total by 1.4.

Thanks John, that is pretty much what I thought but I didn't want to get into trouble with charlie brown by making an assumption.
