Stage 1 V8

Hi,
I have just bought a Stage 1 and the LH exhaust manifold is in three pieces. The guy I bought it from gave me two Rover P6 exhaust manifolds, but I am not sure whether they will fit. I have read a thread on here where a later manifold and front pipe has been used, but can anyone tell me whether the P6 manifolds will be any use please?
Thanks.

You can use a P6B manifold. However this won't align with the standard 109 V8 engine pipe. You'll need to have custom pipe/s made. Using a RH manifold from a 109 V8 would probably be a better offering.

Thanks for your reply. Will the RH manifold line up correctly with the pipe or is there some tweaking involved?

The three studs are now in different locations - test and adjust.
