Piston grinding for clearance

[Sgt.5point0]

I may need to grind for clearance in my setup and I was wondering if anybody knew if it is easier or harder to grind the 93 hyperuetic pistons?

grinding stones get "gummed up" very quickly with aluminum or other soft metals. Carbide cutting heads "cut" or chip the material off more efficiently. Should work. What's up on the pistons???

I may need to grind the reliefs a little to make the .80 intake and .100 exhaust clearance requirement on my setup since I'm using the stock pistons for now.

I'm going to be using AFR 165's/61cc and either the TFS Stage 1 or E-303 Cam with 1.6 rockers.

Just kinda trying to plan ahead for any speed bumps, wasn't sure if the hyperuetic pistons were to be treated differently than forged pistons. I heard somewhere that the hyperuetic alloy is somewhat brittle? Certainly don't want to try to modify the relief and totally ruin a piston

younot gonan need to notch the pistons with those cames adn those heads... they have a 1.94 intake valve youll be alright with a e303 or trick flow stage one cam.....btu anyways I just notched my pistons in my 91GT with a tool isky sells its around $150 for the tool, i got professional results and my car lives again with a trick flwo stage 3 cam in it!!
