If I remember right, you're running L92 heads. If they haven't been milled, they have a chamber just slightly over 70 CC. Since you have flat tops, and you know the volume of the notches, all you need is the deck height, either above or below the block. You can check this close enough with a straight edge and a feeler gauge. THEN...go to www.NOT2FAST.com. They have the neatest calculator I've found. You just put in the numbers you have and it calculates everything out as you go. Gives static compression ratio, and also dynamic compression ratio IF YOU KNOW THE INTAKE CLOSING POINT on your cam. jJust read the instructions, and remember to put the deck height in opposite of what you think it should be...guess how I know, ..above the deck is put in as a - and below the block is a +. Try it, you'll like it. Ron
