 Re: A Series Heads Port Comparison Great pic.
What differences do you see on the A12T vs GX head other than the drilled oil passage?

Re: A Series Heads Port Comparison hey dd
il post some pics of comparison between the two heads.
Other differences i noted were,
the a12t head has a boss between where the first spark-plug and second spark plug go to.
Extra "bolt hole"(no idea how else to describe it) at the front of head probably to mount a bracket on.
a12t head also has a cast of "7" at its back.No idea if the cast number has any meaning.

Re: A Series Heads Port Comparison I like your lion avatar
I reckon the bolt hole on front is for the alternator bracket. B210 mounted the alternator right side of engine.
