i have a 1400 nova SR, and am planning on fitting twin 40s + tubular manifold. the thing is, i managed 2 get hold of the inlet and exhaust maniflds cheap (and new), but they r 4 the 1300 SR. iver been thold the 1300 ports are bigger, so will i neesd 2 do some head work, or will it work fitting it straight on? if any one has pics of the 2 different ports, that would be great.
a mechanic told me the mismatch may give good torque. good advice, or not???
