Kirk knows what he is talking about, he is a wealth of information.

I once had a 1988 Truck like yours and it was also down on power, had a cracked intake manifold (too much heat), found out that Edelbrock made a replacement intake for the TBI Combo and it was way cheaper than the GM price. Put a Comp 260 camshaft in it and the Edelbrock intake and it not only ran much better it got a healthy mpg increase. I never did replace the cast iron exhaust manifolds but I did buy a set of the 85-86 Stainless GM factory manifolds just never installed them.

Still have the manifolds if you are interested, complete and $100.00 plus the trip.

Good Luck
