JMA Cylinder heads

[fatye30ti]

Bought a 1990 325is a couple months ago and it has a JMA Cylinder head on it. Anyone heard of these? Anyone have information? Can't find any links on the web.

Similar to an amc head maybe?

Yes, it's an AMC head. Looking upside down through a mirror. "C" looks like a "J". Do you have any info on it?

[digger]

its an aftermarket head that is not as good as an OEM head out of the box. apparently less likely to crack though

Thanks for the link. Mixed reviews. Sounds like it's okay to keep on a dd car. With some porting, it'll do better. I'll keep the 885 head on my good car.
