Default Lq9 with rectangle heads
Did any lq9's come with rectangle port heads stock ?
If so what cars did they come in and what are the head numbers
Thank you

no they only come on the 6.2 or larger cid. all the 6.0 come with 317s except for the higher end ls2s. The ls2 and newer 08+ Silverado and corevetter engines have the 243s and 799s.

This is not correct. There are a few series of 6.0 engines that came with rectangle port cylinder heads. The LY6 is an example that comes in trucks. The L76 is an example that came in cars (G8).
