Never mind

So I have searched everywhere, and am only seeing spotty information at best. Is anyone running KB399 pistons in a 318? What heads do you have and did you have any clearance issues? I have my block at the machine shop to get it cleaned up, bored and honed. They happen to have a set of KB399 pistons with rings and pins on the shelf from a project that never got used.

They will make me a deal on them, but I just want to make sure they will clear the heads adequately. I am running late 70s 360 heads with the 72cc chambers. It is a 1967 block that was just recently pulled out of the original car. The shop measured deck height at 9.59", and said one side is .002" taller than the other. He wanted to take that one down .002 so they match.

Been searching for data. Even spoke to UEM Pistons tech support. Everyone says the "think they should fit". I am paying to have this block bored, decked and the rotating assembly balanced, so I really want to be careful it goes together without having to change it. Any experience would be appreciated.
The Summit listing for the KB399 pistons states in the "check fit" that they fit the 5.2 Magnum engines. That would indicate there should be no problem with fitment. That said, the usual checking clearances with modeling clay strips must be undertaken. The 6cc dome crowns must be checked to clear the heads intended for the build. They should give fair compression ratio, like 10.5:1.
