Your in luck as I run a 355 with flat top speed pro pistons and small chamber 305 heads.The two most popular of these seem to be the 601 and 416(last three numbers)heads.I have used both and had pretty good luck with them.Others smarter than myself on this forum say that they do not flow as well as the vortecs or double humps, I would have to believe them.I never ran above 6000rpm with the 305 heads.The compression is what I like about them.Oh yeah the other part of your question was the chamber size,which is 58cc I believe.
For low buck racing these heads seem to work well.Some people I know have the valve size upgraded and pocket ported and they seem to respond to those changes pretty well.
