Have you chosen what exhaust as far as manifolds headers or what ever…?? Curious here. As far as plug angle the stealths keep coming up as my personal solution. Having some “ re-worked” tubes on my set up was matched to a straight plug. Not sure if this may be on your list of considerations. Hope all works out for your plan….Swingn’
Headers. Usually, truck headers play much more nicely with spark plug than headers for A or B bodies. I'm hoping regardless of the angle, I'll be ok, but the factory location would be great.
