Aluminum LT1 "643" heads FS

Casting # 10207643

Used of course. Ready to send off for machining!

Valves, rockers, and all still intact.

Looking for $180 now

Also, here's the best for you and me, I'm interested in trades.

If you've ignored my WTB threads, well now is the time to go back and look.

Are the heads themselves straight or will they need machining there too?

Nope. All twisted up like slinkies. Lol

Not exactly sure what you're asking.

If you mean warped, no. Not that I can tell, but a machine shop will take car of all of that anyway. Aluminum is "easier and cheaper" to machine and repair.

I mean are they warped from being overheated, etc. Though. These are LT1 heads right?

How bout you answer me this.

Why are YOU asking?

Take a straight edge and check for light. Have a machine shop check. Machine shops can mill irregularities out of them. Not much, but it can be done.

I was asking as so I could get an idea of how much machining they'd need. That's all dude.

The only reason I ask is..you don't have an LT1?

That's all. Simple question.

Oh yea, LT1 heads.

They are the "most desired" casting # because they have more machineable material to them. Everything's there if you'd want to send them out, disassembled, hot tanked, machined, and reassembled.

I have not checked if they are warped as I was going to send them out regardless and have a good no stone unturned machine job done, and I trust the person they came from.

I got ya now. Sorry dude. You're right no LT1. No reason for me to ask.

Price drop! Will trade for things I'm looking for...
