Header advice needed!

Well for HP shorty headers usually are not the best choice, but the lose is not huge over long tube headers and what you gain in clearance to me is worth it usually. I have run Hooker, Dougs, Schmaucher and TTI and a few others mainly on B and E bodies and a few A bodies back in the day. Of course the problems are always space, clearance, sealing and longevity. The better the brand usually the better the fit and sealing. If you spring for good coating, the better the life. I would say this, get the best headers you can afford and I personally recommend getting coated headers. You want thick flanges and something made for your car body style. Just my $.02
