Thanks for all the feedback
Take a look at EBay 190315483712 what great value something like this is.
As for the heads we are going for a cast iron head with a little porting and larger valves.
Once we get the heads off we will see what needs to be done to the bores and go from there.
As we will do all this ourdelves the labour cost is nil so its only parts costs that count. Given this I think I can do an mild uprated engine for less than a crate motor.
