496 engine build
I have a 496 bbc engine. that was a propane engine before i took it out of my truck. I am putting this engine in a 92 foxbody mustang and wanting to make some performance adjustment to it. I have bought a luncati roller cam, new haromnic balance, new timing chain. i am looking for some heads that woud help produce more power. I have a 400 turbo transmission with an 3500 stall also. and 3.73 performance gears. what are some decent heads for this motor. eventually I want to have a t3/t4 twin turbo to this car. Woud ike to keep it street and strip. any ideas. I do have my msd also for engine.

Do you know the effective head volume of your pistons? Also are they flat top or dished. The best heads for power are Afr, Dart, Brodix.

I've only seen heads and intake for the 8.1 from Raylar and Dart. 12-26-2012 10:01 AM

Better have extremely deep pockets to build an 8.1, as very few parts from a smaller/earlier BBC fit it. Heads have wrong bolt pattern, internals are all oddball dimensions.

No I don't believe I did, didn't know there was a difference.
