Amazing how many people cut their teeth messing about with Mini's, and still know what a 12G295 head is. I could never afford one so modified my 998cc head as per triple C recommendations. Matched the manifolds etc, and had a quick little motor that could keep up with an XR 2I. I agree car engines are much better and efficient these days, but they are mass produced, so I think the rules of marginal gains applies. I've read Roger Parkers book and articles and followed his ideas generally but as said when I looked at the head I thought it could be improved slightly. The must be enough metal as larger vvc valves can be retrofitted, I then re- read my old copy of 'theory and practice of cylinder head modications' and thought yep, let's have a go. Result is very subtle change, which will probably have little effect, but hopefully will improve mid range torque, we'll see (fingers crossed). I agree about comments re suspension etc, and have spent the last few winters working on that. My F now rides and handles better, so roll on the summer, and hope j can get all the right bits back in the right order.
