*Bump* I have the same issue, same year truck, same motor. Anyone know where to get these? I don't really want to fork over $1000+ for the banks headers. Will the "P30" motorhome headers fit these (4x4) trucks? Any help is appreciated!!

*Bump* Im currently swapping a 97 vortec 454 into my k1500 suburban and am also very interested in LT Headers also, I guess the question is will 95 k3500 454 headers with the gen 5 fit on a vortec gen 6 454 4x4? I have used LT headers for a 95 k1500 tbi 5.7 on my old 96 k1500 suburban with the vortec 5.7 so maby with good fitment the headers will fit eachother, these are what im thinking about buying best bang for the buck!! any info would be highly appriciated.

Also if i run LT headers with 3" collectors to 3" duels y-piped to a 3.5" single from the front of the cab over the rear axle y-piped to 3" duals with 45deg 4" tips is this setup suitable for a prochargered vortec 454 w/ the mericurser magnum cam also performance parts to match??

I think those headers will fit fine, does anyone know if there are any differences between exhaust flange patterns between the tbi 454 and the vortec 454 heads? I would think they would be the same, and these headers will work for a '95 which is the new interior style (don't know if that would make a diff or not either)... Also Adam I don't think you'll have any flow issues with the setup you have, but you could run the 3 inch piping all the way back instead of 2 Y-pipes... My truck has the stock exhaust with the muffler cut out and straights welded in with 2 custom tail pipes each going over the rear axle exiting under the bumper...an easy "true duals" set-up while keeping the cats. Throw an X-pipe in there somewhere to even them out and you won't have any issues at all.
