    which headers are best for my 454ed 78 blazer? After instaling a doubler and high angle drive line, my drive line hits the right side header. So its time for some new ones that will clear.

    [/ QUOTE ]What kind do you have currently ??? Normally I promote the Doug Thorley TRI-Y's, but you may want to consitter some "Shorty" header for clearence reasons.

    I third the Thorleys.

    I would choose the Thorleys for better fitment and more torque as tri-y's are intended for torque. They also take up less room since they have fewer number of pipes under there. /forums/images/graemlins/thinking.gif

    What kind of wheeling do you do?
    Yes for torque Thorly is the ticket.
    Only one problem with the Thorly, the hang awful low. Every set I have had an opertunity to see has hung below the frame rails. So if you like rocks bettter put a sign on them that says Bite Me, cuz Mr. Rock will.
    I run Hedmens for this reason. I am talkin First Gen here but I think it's all the same or close enough???
    Hedmen Elite is the flavor of Hedmen to get, they have super thick flanges and heavy gage pipe. Aluminum color coating doesn't change color eather.
    Good Luck

    I couldn't afford Hookers or Thorleys at the time, so I bought Hedman's. They fit pretty well, I had to dimple one tube slightly to clear my hydraulic slave cylinder dust sheild. Both header collectors are about a half inch away from the lower spring shackle bolts, that everyone else seems to have a contact problem with. I think I paid $120 for them, and I'm getting my money's worth!

    Me either, so I have dynomax coated headers. Best $200 set of coated headers I've ever seen. Still not rusty, although they don't exactly look good anymore.

    THe Hedmen Elite is about 270 from Summit, not too bad. I just like the way they tuck up nice and tight above the frame rails. /forums/images/graemlins/thumb.gif

    I'm probably going to spluge and buy expensive headers next time. I've been happy with my Dynomax ones though.

    Hooker Supercomps Best headers I've ever owned/seen the set on my yellow truck has been on for 2 years with out any leaks or changing the gaskets plug acces is excellent as well as plug wire routing they also allow plenty of room to access the starter and oil filter I have another set of these header on my 86 K20 with a TBI 454 that I just welded the O2 sensor bung into also no problems I run aluma-soft header gaskets at the flange and collector and plain old header bolts with red loctite (it's what I had ) also there is no driveline interferance what so ever mine are the none coated version and they were $178.00 FROM SUMMIT /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif

    I've always used 1st Gen Camaro headers on my trucks, they tuck up against the floorboards and don't create ground or drivetrain clearance issues. I did mangle one tube when I wrecked my small block K20, but I was about 15' off the ground at one point, and bent the frame. It killed one tube when the front diff yoke got about as high as the frame rail. On my big block truck I was running Hedman 68190 headers. I haven't bought a new set yet, since it isn't finished.

    sorry i disapeared for a couple days. any way i am running hookers now and i did have to dimple them to clear the hydro slave and on both sides they hit the ord shakles. that was all ok. but after insalling a gen II doubler and atacking upper helldorad the drive line wiped out the colector. now its time to register the blazer(white trash) and it wont pass the safty inspection with out the exhaust intact. maybee the headman elite or some first gen camaro's will clear /forums/images/graemlins/confused.gif

    I have Thorley Tri-Y's on my 454. They fit and look great. I did have to remove one of the factory bumpstops on the passenger side and had to modify the knock sensor connector (I have TBI on the 454) but other than that it was a perfect fit...
