Browsing though what's on offer with the several respected specialist, I've come across a choice of cyliderheads that are supposed to enhance performance:
- Ricardo head (out of stock at the moment)
- Alta head - Brough Superior spec (either cast iron or alloy)
- Nippy / Ulster head (iron)
- Whatmogg-Hewitt head (alloy / aluminum)
I'd like to know what these heads have to offer in different aspects (apart from the obvious price differences) and what further changes may be needed when combined with other inlet and exhaust manifolds and a single 1 1/8 SU carb (i.e. ignition advance/retard; fuel mixture etc) ; no search engine has propped up any useful information (even the posts on the old forum I've found are not conclusive).
