Exhaust manifolds to fit MGB?

Hi, need some info to consider my options, what exhaust manifolds will fit an RV8 powered MGB? There's a set of Janspeed ones on ebay at the moment but it looks like they could foul the chassis rails?
Anyone help?!

If I remember right most off the shelf manifolds will hit something barring the block huggers which are dubious performance wise.

Blockhuggers are option one. But they are a bit tight on flow.
Best option is MGB RV8 style headers. Apart from getting a set custom made these are your best option. They go over the chassis rail and into the inner wing area. So you have to cut a hole for them. The primaries terminate into a simple collector which you can cut back and open up. I've chopped mine back and welded 3" pipes on..

cheers for the info! Bit of an arse then by all accounts, and those headers aint cheap. At least my inner wings are chopped out already the turbos are big lol!

Olly,
MGB Hive do a full stainless MGRV8 system for £495.00, if you don't want the whole system they may do just the manifolds.

I have them and they are beautifully made.
