I am wanting some opinions on a 86 305 block casting number 14088551 and 350 head with casting number 333882.

882 heads on a stock 70's 350 run close to 8:1 compression. On a 305 you can do the math, but I'll bet it's going to drop close to 7:1. Might be an awesome candidate for ridiculous boost, though!
