383 with Eddy heads!

Yeah should have the 318 back and in at end of month.I gonna run it for awhile and piece the 383 together slowly!Now if the eddy heads are too much for it i can go with cast heads but reason i said eddies is so i can get compression up.KB162 pistons would only yeild me 9.1 but kb400 put me at 10.1.Want to be safe with pump gas.
