header size

Is a 1 3/4 header tube to big for my stock engine with no cat, or should I look for 1/58 shorties? I have been looking at dyno Dons and see he sells 1 3/4.
Bud.

Re: header size

I run Dyno Dons on my stock heads/cam 350. They made a very good improvement and the extra flow will be available when I swap out my heads and cam.

His headers are the best for our cars. I have ZERO fitment issues and spark plugs fit really well.
