340 build

I have been buying parts for my 340 build for a while and not sure if i have a workable setup. I have a 68' 340 with "X" heads. The block has been bored 30 over, the heads have been ported and polished and have stock valves and rockers. Has chromoly pushrods and Isky double valve springs, stock crank that has been balanced and the oil galleys chromed. Stock connecting rods with KB flat top pistons. Has Comp cam and hydro lifters (cam is 292 duration and 509 lift), 4150 Holly Street HP 750cfm carburetor on top of an Edlebrock RPM air gap manifold duel plane. The heads have been milled and block been decked. I believe it will have 10:1 or 10.5:1 compression. Any and all opinions welcomed.
