Ported or Big Valve head.

[AlexG40]

There's a chance one of these may become available to me in a few weeks but I'd like to keep my options open as I'm on a bit of a tight budget as I get towards the end of the project.  If you've got either a ported and polished head or a big valve head available I've got cash waiting for the right deal. PM me with info.

Cheers

Alex
