Anyone ever used these heads? Good or bad results? Thoughts on these heads?

I'm not a fan of parts made in China.

Stay away from non name brand heads, I would hope you learned from the mess I inherited, you get what you pay for and after seeing the AFR I just got yesterday I would not even think about going a cheap head.....

Chinese Pro Comps look at the port if you can see it, wish I had pics inside Pro Comp ports.... they suck for flow compared to name brand...

Cheep heads can have many issues one nort often discussed is porting them is a pain as the metal is a bit gooy clogs up the bur quickly. Gets to be a pain picking the material out of the burr.

WD40 on the burr

I dip the cutting bits in transmission fluid.

Works good on the aluminum but not so much for the piece of ham sandwich stuck in the casting.

God's gift to cutting Al.

I would be as much worried about the junk a$$ valves breaking off(which has happened) and destroying everything as the heads being basic POS themselves...
