I am thinking about changing to a new class. The head rule is any steel head 68cc min. What do you think is the best aftermarket head to run?

I run pro toplines, and LOVE them. I have a set on my newest motor, they work great. They ran great when I ran a street stock on 2 barrel and this set runs great on my new motor.

Well thanks for the reply...went to go check out topline heads...but found out they went out of busniess.... so far the platinum iron eagles look the best that I can find.

How much more power do you think the iron eagle 200cc angle plug head would make over a set of 993 stock heads? We have to run a .450 lift cam with flat tops.

I know I replaced my double humps with Iron Eagles and the motor turned 500 more RPMs on a 1/4 mile track.

Protoplines are still being sold by a company called RHS. They have ads in the racing magazines, e.g. circle track, stockcar, etc.

I heard that RHS just bought out topline's inventory, until topline could get back on their financial feet again and start producing after that.

Be carefull though. They haven't fired up the tooling yet and they are simply selling off the old inventory. They have had some serious casting flaws in the past.

Someone correct me if I'm wrong, but I believe that RHS is a Comp Cams company now. Basically comp cams bought protopline and called them RHS. They will still be made in New Zealand, but I'm hoping the machine work will improve with the new management. They did have some quality control issues, but I still thought they offered alot of bang for the buck.

Their was a blurb in Hot Rod or Car Craft a few months ago - said the same thing that you said dgb about being part of Comp Cams and all future plans - can't remember where the magazine is though.

I'm in the same boat for next season and think I'm going with Darts. Pricewise they are all within the ball park of each other. I've just heard more negatives about the other two brands. I know of at least one guy that runs very well with Pro's, one that runs good with WP, and one that runs good with Darts so I figure I can't go too wrong with any of them.

You might want to surf Brezinski's website some ( - they have some informative stuff on their that another member on here reccommended to me a while back.
