Just had the heads off to replace a head gasket, and noticed the headers!

They are BBK short headers and I cant belive how much they restricting they are!!!

The is a big weld all round the inside of the port, making it nearly half the size of the head port!!

I now want a pair of long headers!!

What are the best ones out there for performance??

BBK or MAC. I would take BBK only because it has a 1 piece mounting flange and I don't believe the MAC's do.

Your worried about restiction but not about the loss of back pressure. Even if you go with long tube headers the primary tubes will still be 1 5/8 unless you order them larger. most people that I know of dont step up to larger tubes unless they have big cubic inch motors

Hooker Super Comp Headers are great, you can get them in a 1 5/8 Primary or 1 3/4 Primary with a 3in collector. The are not real cheap though, around $350. D&D Automotive Specialties that can custom build them in 1 5/8 through 2in primaries depending on your heads. They start at $259.95.

Backpressure is never good. Going to a larger tube header the velosity can decrease. 1 5/8ths LT's are probally the way to go.

The weld around the port isn't just because they're shorty headers. Before you I installed mine, I grinded all that down.

I had to throw away a set of BBK shortie ceramics! They cracked in the middle of the tube near the collector and was leaking exhaust real bad. I replaced them with JBA shorties with titanium ceramic coating. These have great build quality and work great. They made the BBKs look like junk. I recommend JBA.
