can anyone shed some light on the mg metro heads for me? Are they any good? What work would i need to do to them? The engine isnt standard bore (not sure what size, but a little bit bigger) but other then that it is a fairly standard setup, i'm also putting twin carbs on the car, so i want it to have a little poke, and dont want the head to restrict the power. Any other advice or questions i should ask when looking for heads? Cheers Ryan |

mg metro heads/also vanden plas im led to believe are the big valve type(same valve sizes as cooper s) normal metro/1275 a plus/injection heads all have the smaller valves it is very difficult to tell what head has what valves just by looking at the outside as unfortunantly the A Plus heads look the same(12g940 is part number across the board) |

Not much really wrong with an MG Metro head. They need less porting mods than others to go fasterrrrrrrrr.

I don't know what year they changed to unleaded for UK but my MG metro engine didn't have unleaded seats in the head when I got it. I had Liddells do the head work and my dyno results are on here somewhere. My car is stock bottom end. Never, ever gets too hot, which is what I like about late model heads. M |

mg/vdp a+ big valve head USUALLY has an extra bit of casting behind the thermostat housing, its not as flat looking as a stock 1275 head, look for pics of john's? Midas gold, its got an a+ head i think, and from memory you can see the differance behind the thermostat. |

As said you can see the external difference in this shot behind the thermo housing, this is a MG metro A+
