well 87-93 camaros/firebirds with 350's would work. i think vettes got the tpi in 86 and got the LT1 in 93 just like the f-bods. you might also consider some vortec trucks heads. if you do, grab the intake too. vortec heads would make alot more hp, but the torque wouldnt suffer like it might with those other 2.
vortecs, are great heads all around they make good torque and hp, but are limited to lift without modifications i think about .480, the tpi's started in the vets in 85, and in the f-bodies in 86, and the lt1 in vetts in 92 and fbodies 93, and the ls1 97 in vetts and 98 in fbodies the vets have always been one year ahead, none of the tpi heads are ganna be much of an upgrade all of them pretty much suck they are alittle better due to the non divider in the intake port like on the tbi heads also known as swirl port heads they really suck, your best bet would be to pick a set of vortecs up with a vortec intake so you can still use your tbi, there are abunch of guys on here that have vortecs for sale for a good price,

The vortec heads are close to 40 hp bolt on over the TBI heads. They are hard to beat for the $, if you are wanting brand new heads, www.SDPC2000.com has better pricing than Summit.

What sort of casting numbers would someone look for? Any vortec heads particuarly better than others?
I'm looking on ebay and see quite a few 906, 12558062 and, 12558059.

Best for Vortecs You can get a great set of vortecs for
12558060 Cast Iron L31 Vortec SB Chevrolet Cylinder Heads Assembled $269.75
At
http://www.sdpc2000.com/catalog/3129...nder-Heads.htm
They also offer a set that have the guides cut ans Z28 springs installed to increase lift
SD8060A2 Vortec SB Chevrolet Cylinder Head w/ Valve Spring Upgrade $339.95
Stock vortecs only allow a lift of 0.45 this upgrade will allow a lift of 0.525 for much less than having it done at a local shop. The base vortec head they sell is a new head cheaper than having old ones refinished at any local shop.
This is something to think about.

Another Idea, This may be the best way to go,

This could be a way to go since it leaves nothing to chance. You do not have shipping costs to a dozen places, and you will not come up against something you need you didn't know about.
"Vortec cylinder head kit provides you with everything you need to install the new Vortec heads on your vehicle.

Intake flow between the 2 should (will IMO) be identicle. Exhaust flow can be equaled though $$'s spent.
"there are only two Vortec castings, 062 and 906. They both flow identical intake and exhaust. There is however, one variation on the 906 casting which has a single-angle Inconel exhaust seat for HD use on 3/4 and 1 ton trucks. This head flows only slightly less than the other two on the exhaust (the intake is the same for all Vortec heads) up to .100" lift, however the difference is so slight it doesn't appear to matter any. These are the heads I used."
****So basically IF you happen across a set of 906's or 062's that DO NOT have the pressed in hardened seat on the exhaust side you will be bucks ahead.*****
