Just bought a complete 1275cc carbd RSP engine and box which apparently is a downtuned MG Metro
Have read that it delivers 60bhp and not 72bhp due to the head having smaller size valves.

Is it just a case of changing the head only to bring the bhp up to 72bhp ??

Cheers

You won't see 12hp just from fitting a 35.6mm inlet valve.
