Default LS1 or LS6 heads/intake on LT1

I've been trying to determine if LS1 or LS6 heads and/or intakes will bolt up to LT1 blocks with no mods. Anyone know the answer?

Thanx 97blkz. I'm actually wanting to know if an LS1/LS6 style intake manifold has been produced for an LT1.

I wish, I think a victor(????) is the best intake for the lt1 but big coin. The lt4 is said to flow a tad better than lt1. One area where options are weak on the lt1/4 motor IMO.

Actually, the LTX intakes are NOT the weak point of these motors. They actually flow really well and can work well with high horsepower engines.

Nope. Different bolt pattern, different valve angle, different coolant passages. Not that it wouldn't be cool if it worked.
