comparing these heads what would be the pro's and cons
35-year-old technology compared with up-to-date technology. The Vortecs flow better because they have better runner designs, have a much more efficient combustion chamber design, and can be purchased brand new for the cost of overhauling an old set of 441 heads and doing some bowl blending on them. IMO, the only real advantage to using 441 heads would be to a restorer who wants an original matching numbers engine.Quote:

The imported alum. from Aus. are about the same price.
Dart Iron Eagle and Pro Topline have the newer combustion chambers. S/R Torquers have the older style combustion chambers. I have used S/R Torquers, and had them bowl blended. They are a good head for the price. But now, I would opt for the Dart or Pro Toplines if I had a choice.
We dont have any alloy heads made here in Australia except for a Cleveland head.
As far as SB Chev heads we have the new EQ cylinder heads being made here that get shipped to the states and they do a brand new 906/062 casting vortec that blows the oem out of the water like they used in the latest issue of PHR and called it a sledgehammer.
The alloy heads however you think come from OZ are made in China All Pro Comp stuff is.
You are correct.Quote:
