I was here earlier saying I was swapping in a 91 Blazer 350tbi into my T/A. I would like to know are there any better factory made heads that would help this setup. Advise on a cam and intake and carb would be great too. I am looking at summit for these parts. Thanks for your time.

 

A set of vortec heads and a vortec head pattern Performer RPM intake with a TBI adapter would wake that up a good bit.

 

there are quite a few different heads you can use, if your keeping it TBI there are couple different routes you can go but it depends if you want to keep the EGR, Edelbrock makes a descent TBI intake manifold that you can find used on Craigslist and EBay and I know where you can get a new cam and lifters for under $100 if your staying with flat tappet
