LT1 LE heads - no springs - need clean up $650+ship
Lowering the cost and reposting...
The heads were first ported by Agostino, then later reworked by Lloyd Elliot about 4-5 years ago when Denny owned them and made 445 rwhp with them on his NA 385, this is the thread they were discussed in.

These heads have 2.0 and 1.56 valves with taller stems so that .600" lift cams can easily be used with them. Basically they where the LE2 package at the time. Heads have been milled by .010".
All of the exhaust bolt holes have been heli-coiled for durability.
These do not come with springs or valve seals and the heads will need cleaning up and possibly new valve guides. The guides are not as tight as my new heads guides are, but I'm not sure how much slack is too much, but they were not the cause of my noisey valve train like I thought they may have been...I have a thread going on about that in the LT1 forum..
Also, there is one valve cover post hole that will need to be drilled out and heli-coiled as the bolt had broken off in it. Its one of the center bolts on the driver side, I went for 3 years without the bolt in it and it never leaked since it was a center post and not on the end of the cover. Pic of the bad bolt hole below.
The valves are all in perfect shape, just need a little cleaning as shown in the pic below. All the valves have been numbered so they go back in the same guide if you decide not to have the guides replaced.
The flow numbers for these heads are also shown in the pic below, they are flow run #3 and #4 for the int and exh in the pic of the flow sheet.
$650 firm + shipping.
The bad valve cover post hole
I would take these back to your local machine shop to check the guides and cleanup and then get the springs of your choice put on brand new. Or arrange for Lloyd to do it as he is familar with this set of heads both when Denny and myself owned them.
