Trick Flow and TEA are part of the same company.

I had rather have the extra compression and forgo the extra flow, unless I was on the hose.

TEA's bench is very Liberal. TFS's bench is a good number.

I also had an exhaust port on that head go 281 cfm, we were just trying to find two good intake ports and one exhaust to digitize.

I have been waiting to see someone buy a set of those heads and post some dyno numbers.

I ran a 5.67 with those proto type heads in my 86 notch at 3100 lb.
