Two problems, The TRW piston will hit the head, down low on the dome, exhaust side where the dome meets the flat part of the piston. Towards the edge of the piston. (these pistons were designed for rectangle port heads that have a bit different c-chamber) You can either cut the dome back in this area or relieve the head/combustion chamber... BUT, with those pistons in a closed chamber head you will have 12.5-1 compression (factory rated). A bit much for todays gasoline..

I would sell the pistons on Ebay (they sell for decent money)and get some Keith blacks with a rating of about 9.5-1.
