There's more to heads than flow. I am concerned that relocating the spark plug might have adversely affected the extraordinary Gen III combustion chamber.

Only thing that would bother me is if it was a sob to change plugs with them like that.

Im sure the new postion further enhanced the chamber if anything. TFS relocates the plugs in alot of their heads.

The price will be in the range of the AFR 205 and uses stock rockers

My thoughts exactly!!

It will be competitive for a Brand New fully CNC ported head

Engine dyno numbers coming soon, what cam would you like to see used?

The exhaust are about on par with the AFR heads, except with a smaller valve, the exhaust actually has more mid lift flow

There are some here https://ls1tech.com/forums/multimedia-exchange/403516-sema-picts.html and the springs are the Gold dual's, same as AFR except they have the polish and plating work, hince the "Gold"

I don't have an exact number, but somewhere in the .030" more range

215 cc intake, 64cc chamber

It is not moved as radically as the LS7, it is moved similar to what Kurt Urban did on his 6 sec LS car, so I think it will be OK.

I was thinking something midrange like a F13. Thanks for sharing the flow data. Interested to see the power difference on the dyno.

According to the posted flow numbers my TEA 1.5s flow as good as AFR 225 on the same bore size on the same bench. Glad I didnt rush to get AFRs!

As long as all their "off the shelf" heads can flow that well, these will take over the market. Hopefully they can produce enough to keep up with the demand that I am thinking will take place.

yeah thats the cam i wanna see dynoed. plain ol' f13 on a 112+4. lots of guys run it including myself. i think that cam would be a good compairison of the heads. and if they outpower afr, it would be great for sales too

Since the heads flow so well I think it would be nice to see results with one of the bigger cams as well, such as a T-Rex, or one of the G5X cams. Any idea on if the CFM keeps rising past .600 lift, or is 325 the highest it reaches?

Will TEA be porting LSX manifolds port match them to these heads?

Acually your not, I was about to say start it off with the 224 cam and then move up to to the low 230 cams and then the all out cams (G5X4, T-rex, Majic stick, maybe even the G5XX). I think id like to see the results form a 224 cam more than anything though.

Hell, I'd like to see you start small (like the venerable 216/220) for us guys that just want a nice, friendly street car. Nothing all out, but with great all around power...plus it would showcase what you can do with a lower lift cam since these heads flow well down low.

What about a 224/228 58x/58x on a 114.

That will be a fun thread.
