Yes, the piston crown measures in at .340 thick at its thinnest point, plenty of material to play with. Also I forgot to mention, the p/v clearance was done with out the head gasket. However as pointed out the cam should be installed as listed, so that with throw the intake valve out a little sooner. I will definitely push up the clearance! Another question; I see Mr gasket has a 4 degree offset crankshaft key available that will give me my 2 degrees advance I need but I assume that puts the harmonic balancer out 4 degrees correct? The cam key is a standard woodruff size so I'll hunt for an offset one as well or perhaps machine one up; anyone know what the offset dimension is for 2 degrees?
I just looked again, my bad, the Mr Gasket offset key is for the camshaft. The Woodruff key is the standard #606. Anyone have a Mr G 987 key by chance?
