70 440, .060 over, TF 270 heads
TF called for the FelPro 1009 gasket.
The gasket bores are not round. On the intake side (top) of the gasket it overhangs the bores.
So bore on the 440 with .060 should be 4.38". FelPro website says 4.41 bore size on that gasket.
I've got plenty of room on the cylinder head to piston - .013 avg in the hole. Gasket is .039, so .052.
Gasket overhangs the bore on the intake (top side of piston) by a few thousandths.
I don't think that's gonna fly. Any insight appreciated.
