Humm 1b715289 shows 2720 standard opti. Port 889639A02 and star889640A02
from my source for the merc parts.
Steel reeds though you you might have a ph swap or reed swap. You might have to dig in the block and find out if it’s a pro or not pull the numbers off the computer and such

Just seeing this and reply to your ad in marketplace. I think you would be better off keeping pistons and just finding you some pro xs heads or see if Chaz can maybe rework cylinder head chambers some to work.

The different pistons may have to do with the different spray patterns from the air injectors used. Blue/black are for standard optis with the wide pattern and grey is for the proxs with the narrow pattern
