patriot heads
No comments means little is known or none are out there? Just thought I would try to get someting going here.
My opinion, they are another Chinese deal like Pro Comp. Probably OK for a street replacement. Probably copies of another head. Probably no engineering for any horsepower or reliability. Probably the components used to call them assemblies are marginal for performance. Probably.
If they are quite a bit cheaper than known good brand heads they are probably not as good for anything more than street use.
