I found this listing on total engine airflow's site.

Look at those numbers, mid-range. very impressive. Though it seems the bore is slightly bigger than the standard 4" used?

These guys are 10 minutes from my house.

Does anyone know if they do good work?

 

I talked to TEA when I lived in Ohio, going in person may net you a better price.

However it should be noted they are using the 4.125 bore [which can't be had with a standard LT1], clay radius on the intake and pipe on the exhaust. This makes for slightly "inflated" numbers which is why I considered other head porters. Go over there and BS with them, they aren't junk, that's for sure. See what they can offer you, saving on not shipping heads across the country may be a deal breaker.

i had them 'drill out' my LT1 intake for a monoblade.
The work was very good and a great price.

I was amazed by the facility. Lots of stuff going on when I walked in there (At least 2 or 3 CNC machines in operation cutting heads when I walked in the door). This was in summer 2010.

The thing I was unclear of is how their head portings stacked up to the competition.

Those numbers are wild for that casting.

 

True they are good, but they have a similar tactic as AFR, using larger bore on the bench, etc.

Actually those numbers are pretty typical for a decent ported 220 cc casting with valves in the 2.050-2.08 range from what I've seen. Well that .300-.400 range is pretty strong but overall looks typical. The AFR stuff typically shows more due to a faster velocity port and maybe due to some bench adjustments to get them to flow more. Flow plates vs clay vs other methods will show significant differences but it really doesnt mean much. Much more involved than just a number the bench shows
