Piston to valve clearance limits?? Engine guru's please read

[Streamln1]

Got a question for those of you that know specs for milling etc.

Here's the situation -

Over the years my heads have been milled a few times.....Before reassembly this time I measured out the heads, they are at 5.170" height, which is about .020-.015 less than stock.

I knew this was beyond the limit, so I compensate by running head gaskets that are .015" thicker so that brings the spec back to what would be normal limit of about 5.185"


Also the engine block has been milled once, it has about .002" max taken off.

So by my calculations, with the thicker head gaskets I am at about .002" over spec, not a lot but I want to make sure I am not going to run into problems.

I have not done anything to actually measure the piston to valve clearance I/e using molding clay, I do not want to ruin one of my head gaskets by taking it apart again and decompressing the head gasket.

So can we figure by the above specs?
