No idea what plugs to chase up .. I put a ported, big valve 161 head on a red 208, will be using Bosch HEI.
Anyone know their plugs ?

Bosch: WR8DCY+ (1.5mm gap) or WR8DCX= (1.1mm gap)
NGK: BPR5ES15 (1.5mm) or BPR5ES11 (1.1mm)
I find our EH is happier with Bosch WR8DCY, or WR8DCX opened up to 1.5mm
Make sure you have a full 12 volts to the coil with either power through a relay or by replacing the resistor wire to the coil.

Bosch WR8DC+

3/4" long thread, gasket seat

That's for the original breaker point ignition and 161 engine.

That plug covers the heat range and physical fit (161 head).

You may find a plug that supports the 1.5 mm gap better. Usually that plug won't retain the electrode gap in parallel if bent that far.

I've tried opening a regular 202 plug to 1.5, not ideal.

You would be surprised how hard WR8DCY+ plugs are to get up here.
I've been told there is no such thing, they aren't made any more, unobtainable etc. Then I'm usually offered NGK plugs. That's why I have opened them up when I couldn't get the 1.5mm plugs.
