How Small of an Engine or Bore Would the A-460 Heads Be Recommended?

Would you use A-460 heads on a Tunnel Rammed 468 CID(Std Bore +.040) with 13:1 Cr for a Bracket Car or a 528 cid Pump Gas street machine which needs torque to pull a heavy Pro-Street Lincoln?

i'd use the A head for that type of build, but then also use

With a 2.300 valve I'd run them on the .030 or .040 stock bore.

I'd avoid the TFS tunnel ram and use a Motorsport single 4 on the small engine. Also watch the port sizes on the smaller inch engine it's real easy to make a pig out of a small one with way to big of heads.

As far as a street drive 528 in a big ass Lincoln, I'd be more inclined to use a P-51 or a SCJ, unless your not worried about how fast it really is.

Yep,bigger isn't always better in some cases.
