A little Help with my Heads. (Motor 2)

It's been awhile since I've been in a stock 360. If need be, I'll compare it to a 360 I have as a core in the garage later if you wish, no problem. But they do look stock being down the hole a bit and with the slight dish without valve reliefs.

What you do to the heads? Are they for the 408 or for this engine just to run well? Try and clean'em up and have the valve seats reground.

IMO, I'd find out just how far down the hole the slugs are now and if those heads are for that exact 360 and not the 408, I'd mill'em a bit and use as is.
