Paul,
You will probably pay twice as much as needed at NAPA. Where are you located ? Did you ask your machine shop if they can get them for you ? I can get the intakes for $11 and the Exhausts for $8 Your machine shop should be able to match that price. Eloy brand from SBI

I merged your identical threads. You'll get a better answer sooner if all responses are kept in one thread.

 

does that include 77- 80 350s

 

Are you getting a valve job at the same time on the heads? May as well just stick some 1.62/2.00” valves in it. Same stem length. I can get you new valves for around $90 and performance springs for $70.

 

The 1977-80 350s got 1.875" intakes and 1.502" exhausts
