I'm doing a gt40 build up (heads/intake) and will of course need some gaskets. I was looking at this set:

I know the upper/lower intake gasket won't fit but what about the rest? I also plan to mill my heads a bit to straighten em out so was wondering if that head gasket would be alright. Lastly, I hear people port matching to a felpro #12xx intake gasket, is this a good gasket that is recommended?

most of it should work fine

looks like a good price, I paid $85 for the Ford kit which is Felpro
