Block decking, manifold alignment, etc

First, has anyone ran a trw / speedpro 2256 piston with Zero deck ?

I'm running a .510 lift camshaft with 72cc sportsman-II heads. Curious if anyone has any sort of valve contact running zero deck and a .041 quench area.

Also, anyone running a Zero deck (I think the exact height will be
9.003 but I may be wrong) with this or similar piston, have issues with the manifold alignment / sealing ?

there shouldn't be any valve interferance issues with that little of life but it's always best to dummy the engine and check for sure. usually you need to start to worry around .65
