Reply to "Any comments on these Al heads?"

TMD advertises the heads are made by Pro Comp.

Pro Comp is an Australian company selling Chinese manufactured rip-offs of other companies products, with substantially poorer quality. The Aussies don't have a very high opinion of Pro-Comp.

The heads are copies of the CHI 3V head. You can expect they are cast with a less expensive alloy, the heat treating is not up to par, and the machining is not as well executed.

Beware of TMD & Pro Comp.
