I am building a turbo sbf streetcar and I'm ready to buy my new heads. I am going to buy the baddest reliable (no leakers) Highports I can find.

I am on the fence with TEA 250s or Fox Lake 244 Stage 5s? Or is there someone else that has a more efficent cnc program?

I have bought a few sets of heads on past cars from TEA and always had decent results. However, I am leaning towards the Fox Lake heads due to them flowing a little better at the lift cam I am going to run (650 lift or so).

Any thoughts or past history with these heads/companies? Thank you

Here is what TEA advertises currently on thier 250 cc highport

Here is what Fox Lake currently advertises on the 244 Highport

my friend bought tea 225 high ports a year or so ago. they steered him clear of the bigger heads (240cc and up) because the material was too thin between the int & ex ports for a turbo application.

Id look into bes or even them overpriced mfers at Bennett. They both have cars with highports flying. I do agree above that a 225 HP will go pretty Damn fast as is in a turbo application.

I went with the TEA 245's and am very happy.

TEA 225s here

Thanks guys for the input.

I think the 225s will be on small side for my combination. I already have most of my shortblock (461") minus pistons.

I know Kurgan has or had the stage 5 Fox lake highports on a smaller motor running high 4s. In order to do that I would assume he had to be using 25+ lbs boost.

Thanks again

isn't kurgan's combo s/c? tea told my friend that s/c an no2 was fine, but i guess it's a heat issue with the turbo applications effecting the thin material between the ports.
that being said, a few months later, they recommended 240cc heads for some other turbo guy. so i don't think they're very consistent with their advice.

I have had 4 sets of TEA's and they flowed above the claimed numbers on the website. I had 1 set of foxlake and they were within 10% of advertised....below posted numbers. TEA has great turn around as well.

Kuntz had a big ol' program for the high port.

I own a pair

 

[Trace Meyer]

TEA ftw! I had a pair of their highports and was very happy with them.

3 sets of tea here. All good

They are perfectly consistent with their advice.... the New casting 240 has a thicker divider wall than the 250 and the old casting 240. After the issues they had with the 265cc LS heads breaking through.... they don't like the bigger port programs on the turbo stuff. They adjusted the bowls for the new casting so the reliability of the 240 hi port on the turbo stuff was better.

Do the new 240's still seem to be holing up OK? Every mess with a set of HIP casting high ports?

I haven't been made aware of anyone having any problems with the 240's. I have 3 sets running 7.70's to 7.90's currently for at least 2 years on customers cars that I sold em.

I haven't done a set of those Hip'd yet but I have done probably 2 dozen of the Hip'd LS heads. They can have that process done on them no problem according to TEA.
