Super Stock Heads: Cast vs Aluminum Replacement

Alan Roehrich · 02-15-2015, 10:03 PM

Aluminum heads are much easier to weld, and once welded, less likely to crack. Iron heads that are welded will crack, sooner or later. Most every head run on a competitive traditional Super Stock engine gets welded.

I'm interested in this too.I have a 95 mustang sitting in the garage with no motor or trans. Thinking about putting something together with a 306 and the 60367 heads and bracket racing it until it gets fast enough to run well under the gt index. I would need to figure out what year between 82 and 85 had the best carb option to claim.

Kent the 82 is a 2v only. 83-85 is the same carb, a Holley 4180. The aluminum head removes the dedicated casting number for the year your claiming in SS for Fords. So it opens more possibilities on combos. The replacement heads are in no shape or form, bolt on class legal based on CC, runner volumes, and valve sizes for the year being claimed.
