another j head question

Thanks moper and BJR. I dropped off my heads yesterday. Talked to the machinist and he has done j-heads before. He wants to split the amount of material taken off the intake side between the head and the intake. After disagreeing for awhile I told him O.k. I know that makes my combination a custom fit. He told me he will give me all the dimensions so I will know how much to remove from a new intake if I want to change it out. He also wants to do a test fit on the manifold before removing any material.......That I agree with, better to check and recheck before taking too much and scrapping my manifold. Of course he is doing a pre and post cc of the chamber too.
I will let you guys know how everything works out. I will also be swapping to a 650 eddy from the 750.
