A comment on cams. Everybody's needs and preferences vary. You have choosen a big cam for a mostly steet driven car. You will get the drawbacks of a big cam - low vacuum, power brakes won't work without a pump and soft performance in the common street RPM range of 2000-3500. Getting decent performance will require a high stall convertor that will make a lot of heat and burn a lot of gas. With standard port heads you won't get the benefit of a high RPM top end charge.

You may enjoy your car more with a smaller cam that gives better mid-range performance... the push you back in the seat torque that makes BB wedges fun. Something in the 240-250 degree @ .050 range.

With the 250 ish cam you would probably be OK with the 10.87 CR. With a 240 ish cam, CR may be a little high. Adding deck clearance to drop CR won't help either since it takes away the benefit of quench. If you do want to drop CR, a litle bigger dish is much better.
