[fun in dirt]

I went this last go round with the same manifolds you are talking about from Speedway...love em! Every vehicle before I've had headers, but unless it's some super big high HP motors I will do manifolds from now on. So much easier to change spark plugs & no more headache with routing & melting plug wires.
I feel you on the shorty plugs; years ago I had a Chevelle with angled plug heads & that's would fit in them = total PITA!
