Hi all, I am having to refurbish my whole engine, and need to sort a refurbished head too. Anyone got one laying around with bigger valves and better flows? Mine is a flat bottom type using bowls in the piston for clearance.
Just for my knowledge, is an unleaded conversion needed in a 7 or should i keep the money and spend it on other parts for the engine?

Surely you have to convert for unleaded? Can you still buy leaded fuel?

It's just the cost of an upgraded valve seat for each valve, or just shots of lead replacement each time i fill up i guess. Am waiting now for a reply from a company selling a tuned head, but probably without hardened seats.

Hi ya Scotty,
I think I have now sorted the head, by buying a ported one, but it hasn't been delivered yet today when it was meant to be.
I'll keep your offer in mind if that's ok.
