It's a little sad after all that work, we go and bolt them on....all the pretty stuff is now on the inside, and will get covered in soot! |

That looks like the ports have not been touched only the chambers are cleaned up. Looks good though. |

its hard to see with the valves in but its all been opened up a little, and cleaned up nice and smooth, its not a extreme port, if only i had the before photos intake and exhaust ports where heaps smaller than the manifold gasket, now they are the same size as the gasket openings, i guess every head seams to be cast a little different, i may have had a real bad one |

my god that looks good! 
I'd put a sheet of glass over the top and use it as a (very)small coffee table!! Cheers, Skender. |

Surely you're not going to ruin that head by bolting it onto an engine!? Another example where they didn't come out of the factory looking that good

Nice clean mild head, well done,,, it`s often not much point opening the ports up much for a roady,,, & often quite detrimental (depending) the biggest restriction is at the valve & seat area,,, std-ish ports are are just fine for most road/rally minis Nice job But yes paint it right now as they go rusty very quick |

yea it was a top job, i am a little worried about the chambers being 22cc, means i may end up with a final compression of around 10.5:1 which i dont know if that would even run properly unless on avgas |

I run 10.5:1. Runs fine on 95, but better on 98 |

10.5 will be no troubles I'd hate to think what my 202 head mega skim on a 1152 is

Well it all depends what cam you use. The more duration it has, the higher C/R you can run. With a stock cam, it would ping its head off (pun intended) on 95. The Cooper S was 9.75:1 stock, and they were not real happy on 97 octane leaded Super. |
