10.5:1 JE pistons with -2cc reliefs, clear milled heads w/ TREX? Like the topic states. Call me lazy, but i just want to avoid flycutting, any additional steps/time that can be avoided are a plus in my book since i barely have time to do anything anymore...
With the standard comp ratio JE offers for non low compression pistons, which i think is a tad above stock. (10.5:1?) Are the -2cc reliefs enough to clear slightly oversized valves ( 2.02 int 1.575 exh) with 66cc ls6 heads milled .030 with a TREX V2??
Thanks to all that help!

2cc is approximately .080>.100 deep IIRC if so it should be enough. Measure how deep the reliefs are (let us say X amount)
If X-.030 is less than .050 better measure PTV with cam in.
