More specificaly the right hand (o/s) manifold or header on a Rover V8, due to a major lack of space caused by starter, steering shaft/coupling and engine mount, would'nt even get a block hugger in there, car previously ran a Rover V8 but motor was dry sumped and was chassis mounted probably creating more space.
Was thinking about buying a left hand header for the right hand side (plenty of space on the non starter side), so would run one manifold backwards (with the downpipe crossing the front of the engine) and the other side mounted normaly, would this be the best solution ?, also are the exhaust ports on Rover heads mirror image ? i.e will an opposite side header bolt straight on ?

TVR did it, so I see no reason why not. Chimaera  Griffith  |

Seen it done on a v8 Manta years ago. I think they do it when turboing Chevy v8s too.

Did consider TVR manifolds but don't have the space in front of the engine for the huge 'Y' section.
I know there have been cars with backward manifolds, has been done in Zephyrs and Zodiacs to fit Ford 302's in.
What i was wondering is if there'd be any problems running one manifold backwards and the other normally as it would effectively mean two different length exhausts.

Do not take my word for this, but if the earlier Rover V8 manifolds for the Triumph Stag were the same as the Triumph 3.0 manifolds you may be in luck. Both of the manifolds exit the front of the engine. I would show you a fitted picture but I have yet to fit mine on yet! Here is a photo of mine on the bench to give you an idea of what they look like. The manifolds exit towards the front of the engine when fitted:  You can just about make out where the manifold exits in this picture. I believe the tubular manifolds take a similar path:  |
