What is a good set of street heads to run with my TR220 / 114? Note I've got an M6 and SLP LT's /w cats. Other mods in the sig.

My car is a street car so maximizing midrange torque is much more important to me than, big HP numbers. I'd rather show you my tail lights than show you dyno sheet if you know what I mean.

I'm thinking about the TEA 1.25's or the AS stage 1.5 heads. Would the 5.7's or 5.3's be better?

IMO 5.3 but now there is AFR's appearing on the scene.
For a "small" cam like TR220, no need for gigantic ports. Just good flow and velocity and a little bump in CR doesn't hurt.

I just got AS Stg2 5.3L's with 11 to 1 CR dual 978's. I'm running an old man's cm CC 216/220 .525/.532. Eventually I will be going to a TR 224 .563 on a 112 LSA. Give Jay a call 1.516.987.9392. TEA's are the other option but I would look at the 1.5's.

East side does a real nice set of street style heads. My buddy runs them and mad 430 with a mild cam and bolt ons threw cats and 3 glass packs, yes 3 glass packs!
I run there raced preped ls6 heads that are un real!!!!! cnc, hand Ported/polished. very nice stuff for reasonable pricing.

With the TR220 being small, is more flow better? I'm thinking some of those big flowing heads would kill my mid-range torque.

Is there a range of flow rates or port volumes I should be looking at?
