Cam phase suggestion advice

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?


Unless that piston has NO valve notch, you have something wrong.

There ain’t no way in all of hell with under .500 lift that valve should hit the piston. Not even close.

So something is really wrong, unless I don’t know what Lunati “702” you have, which is possible.

FWIW, I never regard a cam. Ever. You will gain some intake P/V clearance, but you give up way too much closing the intake valve later.

If you are worried about CR and detonation then call a cam grinder and buy a custom cam.

And keep the engine temp at 180 and no more. 170 is better and 160 is better yet IF you don’t need a heater.
