I have a set of rectangular port 291 LS6 cylinder heads they came off the same engine but the dates are A 20 70 and C 6 70 seems far apart to be a matched set but I guess anything is possible. They will need to be freshened since I do not know any thing about them. 1400.00 for the pair.John 630 333 8333. Please email for pictures to [email protected]
