I Searched and I couldn’t find the info I needed from anyone using these heads with the combo. The domed pistons are almost the same shape as the stock 273 high output domed pistons which were used with the same heads im looking at. However they are t stock and non stock pistons tend to come closer to the deck at their lowest point than stock replacements. I really think they’ll work, and worst I’d have to grind down the part of the quench pad between the valves. But yea sadly no undo that helps me :/ I know the lowest point of the heads and highest point of the piston but it’s sorta the area right in the middle. I wish I had a model of each part incCAD I could look at, I tried to find a downloadable small block mopar blueprint for cad but could t find one for the entire engine
