Default Converting LS-1 headers to LT-1 use

I have a set of Edelbrock Victory Racer longtubes. I was wondering how difficult it would be to convert these headers over to use on an LT-1 block. Aside from cutting a new flange to relocate the primaries, what other problems do you guys think would pop up?

Is the LS-1 a taller engine than the LT-1?

Im not sure but the angle of the exhaust deck surface on the head may be different than an LT1.....i think it would be pretty difficult to cut the primaries, bend and weld them on a new flange in my opinion.

The ls1 has equal lengths between the exhaust port on the heads like a sbf.. the lt1 (and all regular sbc's) have the two ports in the middle of the head right next to each other.

Just buy some lt1 or sbc headers.

use SBC headers. they bolt up to the LT1.. no fabbing needed...

and with the millions of diffrent headers for SBCs out there, one is sure to fit.

Thanks, I kind of figured that. A friend of mine was asking because he thought he might buy the headers from me if changing them over was easy. Oh well, gues they're going on Ebay.

I appreciate the offer for a trade, but I traded my T/A for a GTO. The headers I'm going to ask 800 for those. I had them and the Y-pipe ceramic coated, but had to trade the car before they were installed. PM me if you're interested.
