A good friend has a set of heads that have been sitting in the garage for awhile and have no use for them. We are trying to figure out what they are off of and if they are worth anything. I think (no expert) they are 70 or 71 LT-1 heads.

Here are some pics of the heads.

Those are 75cc LT1 heads from 71:

3973487....71-72...350..........1.94/1.5 or 2.02/1.6 valves, was also used on '71 350/330hp LT1, 75cc chamber


Nothing really HiPo, even the fuelie (camel hump/double hump) heads of years before are marginal when compared to modern heads. Not worth much either, unless someone has a 71 LT-1 and is looking for these heads.

Looking a them, those are the big valves, 2.02's.

No clue what they're worth, but the set I have always worked pretty well.

They also have the special "O" rockers. Good heads--same ports as the 186 or 041 heads just with the large chamber. Worth something to a restorer.
