Default PRC 5.3's

I need heads bad... and seeing how the tax return is coming in... I like the PRC 5.3's stage 2.5 for the money.Am i going to run into valve clearenace issues with a -4cc flat top piston, Trex cam (7.4 rods and 1.7 rockers) and the 2.02/1.575 valves????
Oh yeah thinking about a decent sized pill down the road too

Should be fine with -4cc reliefs. I'm running PRC 5.3's (2.02/1.575) milled down to 57cc with a bigger cam than the trex and I have almost .200" clearance with forged mahle -4cc flat tops.
