Correct plug for 308 heads?

[LXguy]

Hey All:

Have a roller 360 with 308 heads on it. Auto parts store tried to give me the same one for an old-timey 340, but that doesn't work. They do not take the standard LA plug. It is way too big to go in the plug hole.

Do they take the same plugs as Magnum heads?

Any help appreciated.

Thanks,

Steve

they take 14mm, 3/4" reach, gasket seat, projected tip plugs. Autolite 63 is what I use
