99H834AJH was the common or garden variety smog 998 fitted to 1977-78 Clubby S and 998LS.
Chambers in a 998 smog head are just like any other 998 (except Cooper), the ports are small but can be made as big as a 202 one can, it just takes more time.

It's a pollution control engine, probably out of a late 998 Clubman. Or a Mini Clubman S. Or a Mini Clubman Van. Or possibly out of a Mini Moke. |

other than the carbon canister and all the associated plumbing what is the difference between a dirty 998 and an emissioned one? |

A bit of paper somewhere that says it's cleaner . I'm not sure which versionit was , they started with the charcoal cannister etc but then later (77/8) they went to the full air pump system that injected fresh air into the exhaust ports to dilute the emissions gases and therefore make it cleaner on paper . |

Oh , the head may have had a slightly different combustion chamber shape but not much really , main difference was the add on things like air pump and plumbing . |
