I'm thinking of swaping my gt 40 heads ,which are still stock,for a set of the tri state heads .They are gt40's that have been ported (64 cc chambers) and bigger valves (stainless 194 intake and 154 exhaust )installed along with 550 lift springs and the price of 550.00 seems like a deal.Has anyone triad these heads or the tri state services???

 

actually, they are gt-40p heads... and your headers wont work on them

 

Tri state offers both the gt40p and the gt40 heads.

 

Do they give you a flow chart with the heads. I'm curious what they flow from .100-.600 lift. If they can't tell you I'd steer clear.

 

mind showing me a link to the GT-40 heads they sell... im pretty sure you are mistaken

 

tristatecylinderheads.com then page performance parts and heads bottom of page (5.0 high swirl heads 550.00) and (gt40p heads 598.00)are listed on bottom of page

lol those would be the E6 heads which came on the 86 mustang. those are NOT GT-40 heads, they are a totally different casting

 

Thanks for all your help on this AdderMk2 .I was about to make a BIG mistake.I believe i'll just have my gt40 ported and go with news spring package and a steeda #19 cam which was my original plans to begin with.

 

where is everyone from? i am from evansville and i didn't think anyone from outta town knew about these guys. i guess they are a bigger company than i thought.
