Bugger. I wote a whole post then lost it when something else decided to load up in the same window. Grr.
Thanks both of you. As I said, I'm hoping for 150 horses, but thats from the whole lot, not just the head. There would be some benefit from having a fresh head with OS valves, but it's about the whole thing as a whole. Stock is 105 so that's pretty decent without spending a heap, I just hope the tired bottom end can cope. I can't really say how much the head cost. I bought it as
a package deal from a nice guy on the OCC list who is moving over here. Don't know how much a head would cost to recondition on it's own, but I'd hate to think how much it would cost to do the whole engine.
