tpis heads

Anybody running the Tpis heads? They port swap for your heads. Wondering if anybody has opinion on them who has used them.

Curious, what it would cost you?

Have o figure another 50-60 to ship your heads back to them.

All said and done, might be better to go aftermarket if you're out more then 300-400 bucks.

Most out of the box aftermarket heads will keep up with ported stock heads...and have more room for improvement for future upgrading.

Just trying to keep a stock looking engine, but i am not opposed to picking up horse power. The Roc is putting 196 hp 245 ft/lbs at the wheels. That is with 175000 miles on the engine. Never rebuilt. It is going into the paint booth in two weeks and would like to get the engine freshened up.

I see, but IMHO, I think it's going to be too much money, just to look stock.

A set of Darts, Edelbrocks, AFR's..etc...painted black, will still look stock and perform better.
