why won't Hooker headers work on a 96 LT4 eng?
I just got off the phone with the tech at Hooker headers who has just unformed me that their short tube headers #2061 HKR will not fit a 96 LT4 engine. they'll fit all LT1 engines 92-95 but won't fit a 96 LT4.
dose anybody know why these headers won't fit a LT4 engine? can they made to fit a LT4 engine? from a exhaust stand point what's the difference between a 92-95 LT1 engine vs. a 96 LT4 engine?
thanks boonie

First I've heard of it. Being said though shortie headers aren't worth a whole lot performance wise. They're better for decoration, you need long tubes if you want them for a performance benefit, but that brings up a whole different set of problems with emissions.

OK I'll take a guess, do the shorties have EGR holes and the LT4 does not have an EGR system? If that is the case and your set on shorts a couple of pipe plugs will solve your problem.

I have Custom Polished Hooker Super Comp's (Short Tube) on my Lt4. Maybe there is a certain model of Hooker's that you have to use on the Lt4 (I don't personally accept anything over 5"10, 120lbs 
) ....I don't know... But I do know that I have them. I can post pics if you want to see em.

Jim - did you use the factory catalytic pipes?
The tech guy I spoke to at Hooker said they'll fit, but I would have to modify the catalytic pipes.

FWIW, the cats from '92 to '96 are all the same on LT1s and LT4s.

Reading this thread I was wondering why you went with the shorties as opposed to the long tubes. Everyone claims no performance benefit etc etc....what ya think?

When I got them, we had visual inspections in addition to the tail pipe sniffer. Now that the car is 10 years old and with OBD II they just hook it up to the computer, I could get by with LTs. Maybe one of these days I'll switch.
