Welcome to the site!

The '87 heads will not bolt to the LT1, plus LT1 heads have better flow potential. How much power are you looking for? Mild or Wild? For mild setups i've always like the LE1 kit from Lloyd Elliot. For wild combos I turn to Advanced Induction. I'm making 440rwhp N/A on the stock stroke with one of their combos right now.

So the 87 heads are out.I thought the block was still the same.Ok how does that affect me using a efi intake manifold?do i have to go tpi?It is a truck so nothing to crazy just want to have more sack than the old stock 91 350 that was in it.This is a budget build.can i use the lt1 aluminum heads with the efi or tpi only?

You can use the stock LT1 intake, Victor E, carb intake...whatever you wan't. If your just looking for a little more pep than stick with the stock LT1 manifold.

STILL TRING TO FIND OUT WHAT THE DIFFERENCE IS WITH A 91 350 CHEVY BLOCK AND A 95 LT1 BLOCK.iS IT A DIFFERENT BOLT PATTERN?aS FAR AS HOW THE HEADS BOLT?

The LT1's coolant and oil return passages will not match with the 1991 block without some welding and maching done to the head.
