I'm looking to research new heads for my bone stock L98 TPI. Which do you all prefer? will lt1 heads work? Also what should I look for in a head? Kind of new to this and I want to learn.
Thanks

Asking what head is best is like asking what car is beast. Many, many out there, and it depends on your goals for the project.
What is your plan?
Street?
Strip?
All out race car?
Fun daily driver?
Do you wish to have the biggest and best?
Or just something to run around town?
Daily driver?
Or weekend only car?
Emmissions testing in your area?
what trans?

Take it from a guy who pissed alot of money up a rope. Make a plan first, then select parts.

I'm looking for a streetable ap. Not a daily driver, but not a track *****. Something that will give me a gain of maybe 30-40 horse. I hear the vortech heads are pretty good, but I want to check out other options. I would like to go forced induction some time in the future, so that might be a factor. Plan on putting a hotter cam in it, and also some tpi runners that breath more along with a larger throttle body. The exhaust is already opened up with headers and test pipe.

Also auto tranny and no emissions testing

Back in the mid 90's I ran a set of ported stock 113 (88-91) castings, a zz3 cam and slp runners, along with some exhaust mods. Car ran 12.70@110 mph and was a ton of fun to drive. Great gas milage, and almost acted stock. By todays standards, those numbers suck, but it was a fun, reliable, srong bottom end combo. Also, real inexpensive to build.

Thanks for the reply. That does sound like a economical settup which is nice. 12.7 isnt too bad... What would be your recomendation on an intake manifold? I know midamerica sells one they call "high flow" for the tpi's...

Put you money in the heads, cam, and LT headers first. Those intakes aren't worth the money IMO.

AFR advertises thicker decks for FI applications. And, they flow very well for their port size -- maybe the best bang for the buck out of a new head.

AFR 195s -- even with a stock cam -- should gain more than 30-40 horse. Put a cam, short-runner intake and FI on it and you'd have a rocket. FI+TPI would = tire shedder only.
