TTi shorty headers v ministarter

Has anyone had this issue?
No. I ran a mini and TTI shortys on my 68 Valiant.I would check to see that you have good grounds.
Like you stated there is plenty of clearance. My buddy had issues sounding just like yours and is was a ground issue. We added a ground strap from body to engine and starter to K frame that cured his problem. My 2 cents.
