Cleaveland Heads

Ok I know there are 2v 4v heads and then Australian heads. But what does everybody mean buy open chambered heads and quenched heads? Which is better for which application?
Also I heard that Australian cleveland 2v heads are better for getting that power everyone wants. Is there a specific year of head to look for. I have friends in Australia that offered to give a hand finding some heads for me but I don't know what I should be looking for? Any help is always appreciated

The open chamber and quench head are describing the combustion chamber size. Open chambers had larger chambers and usually were on low compression engines. Quench heads are smaller chambers and were usually on higher compression performance engines.

You can use quench heads and dish pistons for more streetable compression and better flame travel. Many open chambered heads were quite prevalent on SMOG motors in the 70's.

Try and use flat top pistons on a street motor if you can get the comp ratio you want. Better flame travel than domes. Hg
