I see trick flows every time I open my hood.

We are running a few more test sets right now guys. I'll try to get them on vehicles asap for more testing & dyno testing guys.

I'm not building them to be as good as anybody else's products in the world. I'm working to make sure they dominate the competiton. That's probably why I have over a year tweaking & testing

I must admit, I was a little suspicious of these claims at first. However, after seeing the development and pricing of your new stainless steel headers offered at almost half the cost of the competition... I'm curious to see just how much power you can squeeze out of these and what kind of prices you'll be marketing.

Keep up the solid work guys!

No need to be suspicious at all. Think about it we offer the best bang for the buck 4th gen headers, probably the best all around 5th gen header. The highest flowing cathedral heads at the hot rod magazine shootout, the only ls7 head to break 400cfm at the hot rod magazine shootout. The leading ls3 aftermarket casting cylinder head, the leading LS camshafts all dyno tested & developed... The list goes on & on. We work very very hard to build the best product we possibly!!

You say the prc had the highest flowing cathedral head in the hotrod magazine shootout
Are you sure on that one?
I just read the hotrod article and PRC was the second highest intake flow so yea they are very very good but they didn't come out on top. maybe next time there is a test of some sort they will be victorious.

solid roller & as cast sounds like a strange combination! LOL

I do however need another tester for these things. We're installing a set on one of our guys z06 vette the first of the week.

Count me in. I've got long tubes and your guy's true dual system. Put on those heads and spec out a cam to go along with them and I'm game.

I'm running a set of your 5.3's right now. Went 450/450 at 5k. Broke a comp pro mag before the tuning was finished. I have to pull the heads anyway to open up the pushrod holes for the shaft mounts, might as well upgrade

We just baselined a z06 for before & after numbers on it. I'll try to get another test car lined up pretty soon.

Great job TSP!! It is impressive to have a shop in house all their products. Shows you how much they really want to produce some of the best products for us customers.

Not bad, about 30 rwhp and 22ft lbs for just heads, if you add a FAST intake it will easily break 450+
