Canfield heads

[twisterf5]

i got a deal on a set of sbc 220 68cc alum head. are they any good thinking of putting them on a 422 with dome pistons would be a roller motor. do you think they are any good and what kind of HP would this combo make.

Take this for what it's worth but I did some research on these heads a few years back and they had a issue with cracking. I have no first hand experience with them though.

Had a set on 13:1 compression 406 about 10 years ago. As posted above, one of them cracked, this was between #3 & #5.
