Hi members :)
I stumbled upon a 68H could also be T68H casting number.
Can any one tell me what head this is?

H89 is the best street cylinder head:
* Closed chambers for best power and fuel economy
* bigger valves than GX head
* Water passages below the intake ports

Two versions:
* Oval ports for high-RPM power
* Round-port for lower HP at 5600 RPM. With additional casting number '928'

Thanks bud :)
So 68H is H89? A15?
No where on the head so far could I see H89.
This head will be used on an A14 full race engine.

Skalabala, there are reported two kinds of H89 heads:
* H89 101 head (oval port)
* H89 728 head (round port)
Which kind is yours?
