Cast vs. Aluminum heads and bang for buck..

I don't have an answer; but I sure like the OOTB Eddies on my 11:1, 367.
As a streeter, the instant throttle response is outrageous.
and on the one day I tracked it, she posted a 93mph Eighth mile; at 3467 pounds and at 900ish ft elevation, with a 230*@.050 cam. The Wallace says that takes 433hp
I wonder how much money,
I wouldda had to put
into X-heads
to get that kind of result.
If you plug those numbers into the 1/4m stats calculator, Wallace says that has a possibility of 116mph.

IMO, I got a truckload of bang for my buck, and my bucks are worth a lot less than yours. I sold three sets of pure stock vintage X heads to get those Eddies, and I think I still had to lay cash on the pile;
but I've never been sorry. your results may vary.
