Late 360 Head Question.

[Johnny Dart]

Hello,
I have a set of 360 heads with air-injection ports.(Circled)

Pretty sure I will need to close these up.

What is the best technique?

Thanks.
John

I think the best way is to tap the hole and screw in a pipe plug with loctite.
It kinda looks like you're holes already have threads or am I seeing things?

They are threaded.
Going through my books I found out you should plug them.

Thanks.

I used allen head set screws with sealant. Can't remember thread size though. They screw all the way into the hole and leave nothing sticking out.

Yep,
Allen head screws with some high temp sealer is the plan.

Thanks alot guys !!!!!
