Intake/head spacer for increased runner length
Has anyone messed with intake spacers between the intake and heads?? I have a spare lt1 intake in my shop and a rough estimate of the intake runner length was 8.5 inches.
Does anyone know the head runner length? If I had to guess its around 5 inches maybe less.
I am willing to bet a 1.5 to 2.5 inch spacer would give tq and hp throughout most of the rpm band

Those should work. Dont use the truck intakes, they make peak power about 5700rpms, which is way too low.

Potentially...at least in theory. I believe Jeremy @ Fasterproms said he's going to look into making a set for the LT1. I have run phenolic thermal barrier intake manifold gaskets on previous cars with good results.
