Can someone explain the Pro's and Con's with the visible difference?
Closed chamber is going to raise your compression versus an open chamber head. If running closed, you need to make sure your pistons sit low enough so the valves don't slap the top of the piston
Thank you for the pic. Great looking Cuda, love the decals.
piston to head clearance is fairly critical w/ the closed chamber-quench type heads .the close chamber head is designed for squish, which is that part of the chamber which causes the fuel-air mixture to head to the valve side at supersonic speeds at tdc to produce a better flame front and combustion for more horsepower.
... and mill all the chambers to the same depth as the deepest one of the 8. Or don't waste the time. Quench and open chamber are oil and water. If you don't do a lot to address the issues using them and trying to get the parts close together safely you get oil floating on water...
