360 heads?

[Mopar-Mitch]

When I bought this car last year has a 73 340. I've had other 340's in the past and they both had j Head's. These heads don't have any, x,j, or u but have an II on the front just below the valve cover, they only have a square embossment between the spark plugs.this is the only picture I have at the moment. Are these 360 or just 318?

360's, but it would take less than 1 minute to pull the valve cover and look at numbers

I have a new set of Mopar Performance valve covers to put on, soon as it warms up. What numbers should I be looking for? Thanks! Mitch

There are a few castings. I'd bet they are 587's.

They are more than likely 1.88” intakes too.
