Just looking for opinions on what the best value 6 bolt head setup is. Im currently cathedral port but open to changing if need be. This is an e85 twin turbo deal, looking for something thatd be up to the task at around 1300rw. Bore is 4.125. Seems like the TFS are tough to beat. Anyways let the debate begin- Nick

Trick flows seem to be the best bang for the buck.

Heavy H.P.

I think most will probably say Trick Flow

1500hp - I was just going to say that! If you want to go a step above that, take a look at our 6 bolt CBM Pro X heads. They flow a little better and have a thicker deck. We have hit 1800HP (crank) with these heads.

What is the deck thickness on that pro x head?

You know that is the only spec I don't have written down. I will do some searching around here and let you know.

ET LS7 heads paid 2400.00 for them about 6 years ago. I think they flow about 350. Money well spent in my eyes.

They are a GM casting in the literature...

Shoot I might be able to do that. We have a few we junked when designing the ports. If they didn't make it to the scrap bin, I will cut one in half.

If you are talking about our Pro X heads, they are not a GM casting. And no they are not a China casting either.

What are the valve angle on the heads? I didnt take notice to this in the specs. I may be over looking it but did not see it.
Thanks!

Where is the literature for these. I can only find the normal ones

You guys have nice stuff, need to get the info out there.

I just bought 6 bolt heads, I would have been interested in these if I had known about them. Or atleast researched them
