which intake manifold do i buy

i have an 88 iroc with the 350 tpi and the intake manifold is leaking. Ive put three of those sealers in it so far and everything is fine but i don't like the whole idea so i want to replace the manifold. Anyone have any idea of which one i should buy? i tried gm but they want like 400 bucks.

Leaking where? How? what? Coolant? Oil? Air? What selers did you put where?

so is the gasket leaking, or is the intake cracked?
I would put on a new gasket set before spending the big bucks on a new intake for the tpi.
There is a water jacket on the back of the intake in the spot you described, could be the gasket gave way and its pissing out of there.
is water going into the oil as well?

Unless something is cracked, take the intake off, clean and scrape all the mounting surfaces and put the intake back on. Get intake gaskets and one or 2 tubes on RTV silicone. Put fat beadsin the front and back of the block, run it up the heads a bit. Put a small amount around the coolant ports.
