Combustion Chambers

To those in the know.

I bought a Motor last year that has Ford Motorsport A-heads on it. And I have the Trick Flow A-heads I bought from C. Evans. My question is are the combustion chambers the same on these heads. I'd like to put my Trick flow heads in the motor Seeing how they have all the port work done to them, the Ford Motorsport head don't have any porting done to them at all, other then gasket matching. Will the pistons work or do I have to order new ones to match the Trick flow heads?

The TFS 87cc machined and 91cc as cast chambers should use the same dome foot print as the older SVO A460 stuff.

Just use some clay to check for sure.
