Anyone try the dart platinum iron eagles?

Wanted to build a 12 sec car, then found some 215cc runners for nothing to put on 355.

Th350 4200 stall 4.56 28"tire mech. cam.

215cc a little overkill but had to get them.

Any thoughts? Anyone have them?

They are a very good head. They had their place when aluminum heads were more expensive. But now it doesn't really make sense to spend money on steel heads for a race car when you can get the weight savings of aluminum. My friend had a 355 with the Sportsman II heads on it and it ran really well, but a set of AFR 195 heads would now outperform them. But if I had them, I would find a way to use them.

This a street or track car? With that converter and gear I'm gunna guess track.
I'd use them but they'd perform better with a higher compression like 12.5-13.5 And a good solid lifter, roller cam
But I don't think it will run in the 12's...more like low 11's
My Malibu has a 383, Older Sportsman ll cast heads with a little work done on them, 660-680 lift cam 12.8:1 compression, 5000 stall, 5.13 gears, 14.5x32 tires
Runs 6.40's - 10.20's

Alcohol loves iron heads because they retain heat in the chambers much better vs aluminum.
My car picked up about 3tenths when I switched to alcohol.
Get some compression in that motor and pour the alcohol to it. You'll be looking for a 9" after that!
