Okay...I stand corrected: Probe pistons are currently used in the 347, 351W, and 460 FRPP crate motors; starting in around 2003. Before that, those engines had Speed Pro pistons...

As for your 302 "GT40" engine, I would suspect it has Speed Pro's in it... but you'll still have to check the PTV clearance no matter the brand. It'll either go or no go.
