can i make this fit into a GSL-SE 13b motor... I got the header and the center piece FREE... or an installment payment of $50... but its for a 12A... I called up racing beat and they said that I need the original invoice if i wanna trade it for a 13b...

 

i dont think it will fit, the exhaust ports are farther apart.

 

If you want you can cut the flange in half and make it fit

 

Don't see why it would be so much different than bolting up a TII manifold. It prob. wont flow as well though.

if its the road race style, just cut the rear flange and trim the lower section of the engine-to-headers flange as the GSL-SE has the extra engine mount in the center plate. with the other style, its easier to just cut the front and rear flanges. get a GSL-SE gasket and bolt the headers to it. this way, you can mark the areas that would need trimming. wont flow? the pipes are the same size for 12-A and 13-B.

if you need help, pm me. i think im free this weekend.
