Hi,

Thought I'd start a new thread in case this post wasn't noticed further down. The advice that I received (and that I'm acting on) is that I'd be much better off with twin SUs, a C or D cam and a head change (my wife agrees that a head change would do me no harm at all...)

I was able to source the SUs, a suitable manifold and the cam and followers. The seller also has a B20 head but he's not sure what kind of B20 its from... He reckons that the larger valves will improve breathing but I'm not sure if a B20 head will work properly on a B18 block. Will it work (say with a B20 head gasket)?

I had a quick look at the current B18 head - its marked B18 and has some other numbers but doesn't seem to indicate anywhere that its a B18A head - is there any way of telling a B18A from a B18B etc?

Thanks for all the advice - I learned a lot from yesterdays posts (and saved myself a lot of frustration by the look of it)

Aidan
