SBE 318 basic rebuild +CAM , INTAKE, HEADS, expectations?

Took the top end off..

Has 360 heads on it
Comp Cam 10-268H
Sloppy double roller Timing chain..
Pistons are Flat tops and at tdc are 0.0852 in the whole
If you are gonna keep it as is, there are .028 compressed thickness head gaskets that will help.. not a ton but every bit..

BTW.. buy the trick flow billet timing chain.. it's $100 and quality... not a spot to go cheap.
