If the dish is done right, so that it mirrors the shape of the combustion chamber, you have a very ideal setup. Good quench can be maintained using this method, as opposed to just using a big round dish.

At that point however, you've probably spent the cash to just go with a different set of heads, and not have to tear down the short block to replace pistons.
Since we're talking about a limited budget, changing the heads it going to be the best option.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
