Need Advice on Machining the Intake Surface of the Head (gasket crush)

1970 TA said
I used the washers to simulate the thickness of the intake gasket and limit the crush of the clay. I plan on using the Felpro gasket that leaves the heat crossover open. The gasket measures 0.055 / 0.060. On the drivers side head, that gasket thickness looks marginal on bottom the ports. Did you read the Hugh's reference article? They use steel washers with their wax material.

I read very little from Hughes. I guess I could read it, but then I'd probably be pissed off for a while. I like Dave, and he makes some parts that I use but he and I disagree on most everything from tune up, to port work, to intake manifold and his selection of cam shafts.
