The Pro Top Line heads are cast in China then shipped to New Zealand for machine work. Only problem with this that I can see is the China heads (and there are several brands) don't have any "Verifiable" quality controls in the casting process. They DO NOT have a minium standered for the process itself nor for the alloy. Another words you get what you get, but you don't ever know for sure what that is. I would have no problem at all with the KIWI's doing the machine work.

There are several really good heads on the market. Granted the American heads are far from cheap, but is that actually true if you have to do the job more than once because in the process of trying to save a little money you bought a sub-standered part? Good Luck !!

well no the PRO TOP LINE head s were a true KIWI head .at one time part of the biggest builder of heads for OEM re builders .the pro top line part was pick up by comp cam now under RHS heads .there is another head see them on E bay them are the Procomp heads are casted over in china and machine in austrailia or all work is done in china ship to austrailia for a better pedigree and sold under many names . the head it self needs some work to alot of work but some have made them work they say they have upgraded the head s but will not tell me what they have fixed so i not buying any .... the big deal with procomp heads the bbc was the port it was a 1/2 a$$ size and you had to use a head gasket with a 4.625 fire ring even it you have a 4.310 bore or a small er bore but added time on some so/so heads most of the time i buy darts .as for now and how much is casted in china that is now hard to say holley has gone this way on there weiand line
