Just pulled the heads on my 73 340, looks to me like the pistons are the high compression replacement pistons. Pistons stick above the deck and have 2 valve
Reliefs. I can't find any numbers stamped on them but they are standard bore. Here is a pic, tell me what you think, just making sure what I have before I buy a new cam and lifters.

Yep. Looks like the stock high compression pistons..
 
That's what I thought, the 587 heads have been redone recently, going to cut down the valve guide to make room for a bigger cam and do a
Bowl clean up and use the 1.88 intakes for now.
