Hood clearance

I haven't heard any feed back on how they fit. The price doesn't look too bad if they fit good. Are you hopping your engine up a bit where you need them? If it's a mild engine, the stock manifold should work just fine up to 6000 RPM or so depending on your cam. I've had my 273 HP over 6000 with the stock manifolds....both intake and exhaust. the 318 will breath a bit harder, but, if you're running stock cast iron heads and a mild cam, headers aren't necessary IMO.
