200cc Dart pro 1 platinum heads Ported and gasket matched

Sellling these babys.
These are just as good as a set of afr 195cc heads.

They flow 285-290 on the intake on the flow bench and I have verification that they do.

and 260ish on the exhaust.

They are gasket matched for a 1205 intake gasket and or a 1206.

they have dual 1.437 springs and have part ferrea valves and dart valves. The springs and valves can handle up to a .650 lift cam.

The valves are a 5 angle valve job 2.02 1.60 size\


angled sparkplugs too.

These heads will support roughly 550hp Naturally aspirated pump gas. That is to the flywheel


1050 OBO


this is quite a steal being that afr 195cc are 1500 bucks new. The dart pro1 platinums are 1300-1400 new and these thing are ready to go.
new seals and everything./

any info at which lift these flow figures were reached? also if you have any low lift numbers that would be interesting.

what rpm can the valvetrain handle? are they setup with guide plates?

valvtrain can handle 7500 rpm. I shifted almost all the time at 7200 on spray.

Re: 200cc Dart pro 1 platinum heads Ported and gasket matched

Do you know if the Dart Pro 1's will replace aluminum L98 heads? I'm not sure if the bolt pattern is the same. I currently have a 350 with aluminum L98's and a HSR.

Re: 200cc Dart pro 1 platinum heads Ported and gasket matched

The Holley Stealth Ram should be the same bolt pattern of a standard TPI, if that is what you mean. I can check mine and make sure, worst case I think I can expand the middle intake bolt holes so that it will fit.

Angle plugs give more effecient and complete combustion in the heart shape designed combustion chambers. By angling the plug it aims the spark plug towards the exhaust valve which is the hotest part of the chamber. Burning the hotest part of the chamber first and reduces the possiblity of detonation.

Re: 200cc Dart pro 1 platinum heads Ported and gasket matched

i was wondering the same thing.. sorry kowboy but you haven't supplied a whole lot of info, otherwise i'd maybe have snatched them earlier
also no info about flow other than max flow, and then not even noted at which lift that was achieved..
