Y-303 heads

[J-rod]

What are your all's opinions on the Y-303 heads? Looking for honest opinions and knowledge here.
And most importantly where is a good place (besides corral) to be looking for a good used set?

I have a deal on some GT40P for $200 locally, but the idea of an aluminum head has really got my attention. But if I dont find a deal by Christmas I will get the GT40P and take to the machine shop. Then find intakes.

I am planning h/c/i this winter hopefully as long as I can pull the engine and get it into a garage before the heavy snow flies.

I have a 331 that was built by Fox Lake with their Stage 1+ port work done to a sent of Canfield aluminum heads. The combo was only started and idled in the garage. I'm getting rid of all my fox body stuff and will most likely be disassembling the long block to sell the components off separately. Shoot me a PM with your number if you're interested in any of it. I'm just looking to move everything fast.
