We can use the ProTopLine ProTorker heads this year and I am looking for opinions from anybody that uses them, be it good or bad. We have been using the GM 434 heads that have been opened to 2.02 intakes and 1.60 exhaust. We can't port or polish the heads, We are pretty much stuck with what we get out of the box.

if you are talking about the pro action "iron lightening" heads then they will be way better than any factory gm iron head.

ProTopline may still be in bankruptcy. The heads are made in Austrailia and shipped here on a rowboat. Our's cracked on the matchline in the #5 intake, thru to the water jacket and up accross the valve seat into the combustion chamber. Dart for me next time.

I was told by our supplier that Comp Cams bought ProTopLIne and the heads will be U.S. made.

We have the 50cc pro top lone heads, and love them to pieces. I went with them because they were the only ones to offer the 50 cc with straight plug heads, we have to run straight plug. But if I could run angle plug, I would have went with the experience of Dart Iron Eagles.

pro topline heads were manufactured in new zealand not australia. they have been purchased by an american company but i'm not sure if it was comp cams or not.

My dad own's a machine shop and he sold them to alot of people and also have them on mine to, we haven't had a problem with them, but you do need a pretty get engine to run the heads because they make alot of power.
