I am looking for a supplier for WD 201 flat top pistons, 4 1/8 bore. Agco or A&I dont sell them. I am building a 226 and want to raise the comp ratio.

When I ordered the engine kit for my WD45 my engine shop gave me the choice of standard or "power booster" kits.

Naturally I got the power booster and it came with 1/8 overbore flat top pistons. I am 99.9% sure that it was an A&I kit too. This is going back maybe 4 years now however.
I guess after that its not really a power crater anymore, is it?
