I am glad you chimed-in, Don. I want to improve performance a little so I was thinking of new heads: there are too many choices. I know that the inexpensive Vortec heads require a new intake and valve covers. On a bang-for-the-buck basis am I better off buying some aftermarket heads and sticking with the more common SBC configuration? I want a head that will help now and can still be used at a later date when I install a 350 or 383. Should I look for some old camel humps? I see that the chamber sizes on the various heads vary from 56cc to 76cc's. I think the 305 heads are 65cc and I do not know the stock compression. Recommendations will be appreciated. The car comes with a GM 4 bbl carb.

I found a link to the article I was thinking about..
