i tink the one that aes mentioned should be alright for u ... your 2T kahwin 3T bottom issit the 2TG kahwin with 3T carb bottom? if yess and u using oversize valve you need to grind your valve seat a little.... else your exhaust cam will hit your piston.the original 3T piston have dome shape which will make it a tight fit on the 2TG head.... what i suspect happen to your engine is your valve floats during high rpm.. further more with a reprofile cam you might have more overlap between the inlet and exhaust... i will suggest u do grind your piston surface for your valve seat and at least change your valve spring... else no matter you are using forged or any aftermarket piston the same thing will still happen.. it will either broke your piston surface or it will broke your valve drop it to your chamber,piston hits it and there goes your head ,piston,ring and your cylinder wall
