In the new Jegs (i don't know about Summit) there are Dyno Max Strees Series Shorty Headers. The only F body listed is a 82-92 GM F-Body 5.0L TBI for $289.99 with a $25 mail in rebate. They say it has 3/8 flanges and comes with gaskets, mounting hardware, and Y-Pipe. It sounds like a good deal for
$265. Does anybody have them. Are they any good. The rebate expires this month.

I think that they're 1 1/2" primaries into 2 1/2" collectors. Some may tell you that this is bad. But I read an article in Car Craft were they did a comparison on $99 headers on a mild 350. Although the Dynomax shorties was 6th out of 8 in PEAK power, it placed 2nd in AVERAGE power from 3000-6000rpms. I think they would be fine for a stout 305 or mild 350. Especially street use.

The one's you're talking about are the same as the ones in this test, just add the charge for the AIR tubes. That and inflation. I think those same headers that Car Craft used are now $139 through Jegs. But the ones your talking about are a good deal, IMO.

these headers came with every thing you'll need to install them.they even came with a extention for the o2 sensor wire.the only thing i would suggest would be don't use the header gaskets.get some FEL-PRO header gaskets

There was a discussion about those a couple of months back. I don't remember the verdict though. I will probably be getting those headers myself and having them coated. If they are not good then I'll probably sell those and buy others. That's how you learn. Try for yourself and see. Nothing is ever easy and there's no such thing as "a sure thing".

these headers are coated but it burns off after a few months.when i put my new motor in i'm just going to use some DEI header paint.i've hear dthat stuff holds up pretty good
