Header / exhaust pairing

[chrisd9997]

Bought the 2-1/4" dual glass pack bolt-on set from LMC. Looking for some general guidance on a set of headers to finish the job.

Is your 350 stock or near stock?
I'm about to order Flowtech Headers 11500FLT for my modified 1985 305. After viewing some YouTube videos it seems the Flowtech are a good fit for your truck. 2-1/4 dual exhaust would be fine with a stock 350.
Many folks want three inch exhaust but from what I've learned a 2-1/4 or 2-1/2 exhaust is a better match for a stock 350 or 305. Having said all that I am not an expert. Richard Holder and some other respected YouTube engine guys seem to agree on smaller size.

Any generic set of headers that will fit the truck will be fine.Up to you if you go coated (recommend) or not. 1 5/8 tubes is all you need.
