which a460 head for me?

Post  stanggt on March 4th 2012, 11:45 am

Im gunna get me a set of A460 340 heads. My build is a 572 with flat top pistons and roller cam to be custom built for me and will buy the tfs intake to match heads and prosystems carb. Going in a fox with powerglide and going N/A for now with Frosty in the future. Im looking at the 87cc chambers VS the 83cc. and probly some porting on the heads. which ones should i go with and why?

Thanks,Chris

Isn't the 87cc heads the 10 bolt design and the 83cc the 18 bolt?

You want the 87cc chamber. !0 bolt chamber will flow better and does not shroud the valve near as much. If you dont mind reworking the chambers the 18 bolt will be fine. Lem can get you an 18 bolt head with 10 bolt cnc chamber.

The 10 bolt chamber ...cast or machined always was about 87.5cc. The 91cc thing in the catalog was incorrect.
