LS6 Heads what are they worth

**chrislyn** · 08-16-2008, 04:21 AM

I have a matched pair of LS6 Heads Part # 3994026 Date F-30-71 I have had them in storage for 28+ years. The ports are original in very good condition with no issues. What are these heads worth.Any help-WES

LS6 heads should have a cast number of 243

I think you're talking about the LS6 heads from the LS6 motor that came in the 70 Chevelle, if I'm not mistaken...

1. The build date is F-30-71, which read February 30th, 1971
2. You say you've had them for 28+ years

The LS based motor didn't come out till 1997, so those are not LS-Series Heads.

hmm. Never knew they built stuff on Febuary 30th?? Always thought that was a mandatory day off.

Actually the engine code for the 454 that came in the ss in 1970 was called an LS6. I thought it was a mistake too but goggle it, its true!

Well I have not had anyone come up with a number here on the forum, so I called two rebuild shops that deal in these Hi performance parts and both told me the same thing. they are worth $2500.00 and if I was to hold on to them a couple more years they would probably double in price. They are rare heads. I believe they said that only 188 cars were built with these heads back in 1971. What do you think. One of the shops was in California and the other was in Wisconsin

Lot more of those heads are around than you think. I see them go for alot less than that. 188 were built in 71, but alot more were built before that.
