Simple question, advice needed: Could the head from an EFI 2 litre Pinto bolt straight on? I understand that not only having hardened valve seats for unleaded but also enlarged valve guides to acieve a little more power, but want to keep it carb'd,. If this is the case it's something I've got to ponder for next year, as there is a possibilty that once the bodywork is fresheneed up I night look at tuning the Pinto & squeezing more power out of it. I want to keep it old skool so I'm keeping carbs, altohugh I do have an EFI 2 litre Pinto at my disposal which I could plonk in. Not looking for mega power, just a increase in bhp & torque

So anybody know if this is that easy to do r are there other pitfalls I've got to think about?
