The LT4's have a raised intake port as compared with the LT1. The intake and heads are matched to LT4 and you can't mix LT1 and LT4 intakes and heads. If you want an LT4 manifold you have to change to LT4 heads as well or you have a big port mis-match.
I think Edelbrock makes an air gap manifold for the LT1's, but I really don't know anything about how well they work.

The only test I've seen on the Edelbrock is for the LT1.
So, so results.

If you get the LT4 heads you'll need either the LT4 intake or Edelbrock's version.
Their LT1 and LT4 are from the same casting, it's just machined different.
Stock LT4's command a hefty price.
So long as someone meantioned the AFR's, the 195's will fit you current LT1 intake.
