It just so happens I have $300 to spend...so..would they work in my '87 LG4?

 

Yeah, they'll work. As far as Vortecs, I've only ever read about 906 and 062 castings..I don't know about 193's. And being milled .020 should be good for your 305. Stock 350 heads throw a 305's compression down the crapper. Don't forget you'll need a Vortec style intake. Edelbrock, Scoggin-Dickey, and GMPP all make manifolds. You're running carb? I'd go with the Edelbrock RPM Air-gap, I've read good stuff about that over at TGO.

dunno if id trust the seller though, he has alot of high dollar items on ebay with no reserve and 0 feedback

 

I wouldn't buy from anyone who uses LT1 and TPI to describe the same engine.

 

I was thinking the same thing...

 

Those are not 96+ Vortec heads. Those are 87-95 TBI truck heads. Notice the 6 bolt holes instead of 4? Yes, they will bolt up to your 305, but they have larger combustion chambers, so you will lose compression. No, I dont think its worth it to buy those heads. Stick with what you have until you upgrade to a 350 engine.

 

Those are not vortec heads.
They are 87 and up heads with 1.94 - 1.50 valves.
They are the same TBI truck heads that came on the 1989 5.7L core I bought a while ago to build my 383.
They would make a nice truck engine.
I think they have 72cc chambes (before they were miled).
I saw some new 193 casting made by pro top line a week or 2 ago on ebay, so they must be good enough for people to want new 193 castings.

 

The 193 TBI heads have 64cc combustion chambers.

I don't know if they are exact "clones" because they list as being 76cc chamber sizes when alot on people on this board say they are 64cc heads.


I ran a bone stock (w/Z28 springs) set of GM 193's on a 383 stroker with stock L98 roller cam, performer intake, CC-Q-jet, and Edelbrock Headers.

The Camaro ran 14.8's with rock hard BFG's, open 2.73 rear, and a slipping 700 R-4.

Not too bad, I am considering using another set in a 383 stroker for my '86 K5 Blazer 4x4. It has headers too, along with 4.11 gears, posi, and 33" A/T tires........should be interesting if I quarter mile it someday.

 

Uuuggghhh believe me you dont want truck TBI heads...
