Valve to piston clearance?

Wouldn't that create more valve clearance issues?
So your saying I would need to run race fuel with a 9.5 compression engine? But not with what your talking about? I ran the numbers with the 167 pistons and it put me a ways about 10:1 and high 8s to 9s dcr that sounds more like a pump gas issue that a 7.9 dcr. I'm I wrong?

Yes, that DCR number is incorrect. You're using the .050" ICA fo 38 degrees , not the advertised ICA of 59 degrees. Lunati does not list the advertised ICA on their cam card, you have to figure it out..... I think someone already helped with that.
Use the 59 degree ICA, and your DCR will come in where it should... right at 8.0. That is with no block decking and just a clean up shave on the heads.

Sometimes more is less.
Sometimes a little more money spent on an exact-fit piston, will save you a lotta money on various machinings, therefore actually costing you less.
I think KB performance actually has a teener piston on the books with an .050 Quench-pad on them.I don't see them in my ancient catalog. These will pop up above the deck and you will have to custom fit them. These are the ones I would get. No block machining, no head machining, no intake machining,pre-cut eyebrows, and all the chunks fit together like stock.

A lot of good info above, and a plan that I advocate for this case. The issue is the re-balance cost. Working on solving that with 273 pins.....
