It is the oval port thanks bud :)

So... Who is the most retarded person on the forum?
I vote Skalabala

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.

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

Thanks ddgonzal :)
The OEM A14 gasket I have is oval.
That is why I am asking. Could the OEM GX one be round?
Will be cool if it is for a cheap way to not need to get expensive MLS :)

Hi members :)
I saw this Gasket
It says 79mm bore. But I think it will be 79mmx77.65mm+- ?
How good will the fire ring cope with 78mm pistons when using a gasket like this?

Regards :)

datsunbeginner, it is not a must but it will run better.
Only need to change those thing if you want it to run optimum.
And the obvious reason that you are going to get feed back on your radio if you use plugs without the resistor.
Standard coil is a 9V one and EI is 12V and an EI coil has a different charge time.
Charge time is like dwell angle but you do not have points any more.
Every coil has different inductance and resistance and this gives different spark characteristics.
There is a lot of science behind ignition :(

Remember to get the correct ignition coil and spark plugs for the new set up :)
The spark plug gap spec will also have to change :)
E15 pulsar is a straight fit.

Run in oil I use SAE30/40 on all the engines I build.
The cheapest you can find :)

Driving the engine like a sissy is what causes damage while running in.
