high compression egge pistons for 273

i am rebuilding a 1967 high performance plymouth 273. everything checks out that it is the hp version. when i took the old pistons out they were the flat top standard non hp pistons. the engine had been rebuilt at some point and bored .030 over, it does not look like any of the decks were shaved or any other machining. i ordered egge high compression pistons they are called an irregular dome. the possible issue is that at tdc without gasket on just the domed part of the piston ( horizontal above the wrist pin) sticks out of the block about .060. i called egge and a machine shop and they did not think that sounded right. either the pistons are ground wrong or that is how it was supposed to be from the factory. i know i could put flat top low compression pistons back in it, but i want it to be original as intended. any thoughts besides just to put a different motor in it, the whole car is original and i want to keep it that way.
