Does anybody know if the manifold/downpipe junction of the two engines is in the same place/same size? I know that the manifolds are different (cast vs. tubular, with different shaped ports) but wonder if they can attach to the same system from there on?

No. Flange sizes are different.

That's useful, thank you. About the position, could the same downpipes manufactured with the 2 different flanges fit the 2 different setups? I'm trying to organise a batch of systems and it would be useful if they could fit both engines.

On a different note, is there any benefit to having a heat shield in front of the manifolds on the earlier SOHC models?
