Quick question. Upgrading my heads and looking to also get some new valve covers. I'm curious about clearance for the covers with Stainless Marine exhaust. Do I have to stick with a Mercury 500/525 or Harden style or can I fit a standard tall Big block cover? I think I know the answer, but wanted to make sure. Also, if I have to stick to a cover for marine exhaust applications. Are there other options than what I mentioned?
