Take a look at the trickflow 175s. I'm thinking about upgrading to these myself, budget (wife) permitting. Maybe next year...

If you're going to buy some new heads I would recommend you buy them based on what you plan on doing to the engine later...I.E., Super-Ram, Mini-Ram, etc...
In which case some of the best off the shelf heads I have seen are the Trick Flow Kenny Duttweiler heads, they are a little big for a 350 TPI but would mate up well to a Super Ram or Mini Ram if that's your plan down the road.
If you buy heads for your current TPI intake, then upgrade the intake then you'll also need to do some work to the heads to get the most out of them...no reason to spend the money twice!

If this is an 89 as is in your profile, you do not need new heads. As long as you have TPI on it with the stock exhaust, they are not a limiting factor in your engine.
If you are set on picking bigger heads then you must decide on a future combination.

Alas! My friend the integrity of the Vette will not be lost for the simple fact that the heads will NOT be after market heads they will still be GM Vette heads and not any other brand! Thus keeping the integrity of the Vette! I had a Chevelle and it did not have any of the OG parts and on my Vette I would prefer to keep it all GM and possibly if I install a cam it will be a ZZ3! Anyway it's just what I've decided to do with the Vette this time around!

Don, how is the Cuisinart holding up ? Hate the fact that I miss it. You crack the heads?
Go for some AFR 180's, L98 plug angle.
THink they are around $1400 and change through Jegs
