Can someone help me pick out some headers? searching and reading the boards just get me more confused I have a 1976 K5 blazer 350 small block (it might have been bored over, I don't know? does that matter?), I just want a simple answer and where to buy them at for a decent competitive price. I just don't know how to figure out what header would be compatible to what "specs" I have? carb? smog? does that stuff matter to what headers I can choose? Id like the headers to look good ( not a necessity) bolt on easy with as least amount of modifications as possible and of coarse gain me some good HP.
