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./

 

1100 shipped OBO need these gone!

bump

 

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?

 

How do you gasket match a head for two different size ports ??

-- Joe

 

valvtrain can handle 7500 rpm. I shifted almost all the time at 7200 on spray.
Yes they have guidplates. 500-550 lift was where max cfm was attained

I have flow numbers from 150 lift up to .600 I beliee pm me if ur interested

they are gasket matched for a 1205 but 1206 will work on these too

 

you said these have been ported...have any close up pics of the port work?

 

What size exhaust ports do these have (64CC or 72CC)? Sorry if i missed it.

 

yes i can get them tomorrow.



64cc

thanks!!!

 

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.

 

yes thats what these are for. But the intake will be different than a tpi if you have that

 

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.

 

Ya that will work. Let me know if ur interested

 

who did the port work?

 

Dennis jones at automachine. One of the two best machinists in central Florida

 

stinks they are angle plug, or i would buy them prolly right now. They won't fit Eldelbrock headers. Why does everyone get angle plug anyway??

 

Get better headers lol

 

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.

 

1050 shipped!

 

Weekend special!!!!! 1000 shipped

 

PM sent

 

pm replied!!

 

email me pics of the porting and a copy of the flowbench result. I know someone who might be interested.

Sold!
Thanks,
for your fast reply!

 

there are obviously sold, but what was the poured volume of the port after the porting?

 

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..

 

i was never asked any other questions but sold lock it up!!!

 

The saying you snooze you loose comes to mind, no sense in whining about it.

 

ok so what was the runner volume?
