Boith ACL, and Permaseal make an off the shelf "head saver shim". They are intended to be used when a head has been skimmed so far that the CR/valve clearance is outside usable tolerances. You glue the shim to the block deck with copper head gasket cement. I run one of these, as well as lower comp pistons. (But not much lower, don't ask about these ) It doesn't hurt to run double valve springs either. You can really get carried away with beefing up the motor, but if you're going to go CA, don't get too hung up with it. If the manifold is for a 32/36, just run with that. They work fine. Do you have the crank puley? What diameter is it? I think the blower pulleys are 125mm from memory. One you get it all running, You'll need to frig arounf rejetting the carb a bit. I ran my mixtures really fat in trepidation of detonation. Just check your plugs to guess the jetting, or if you can borrow one use a wideband A/F meter.
and for the love of god, LISTEN TO YOUR ENGINE!!!!!! If you hear it ping, retard the timing. Don't just drive it hard cos it goes hard. There are UMPTEEN stories on this site starting off got my turbo/blown motor going. Then What causes blowby? lots of folk crack their ring lands, and get mad blowby.
Get your set up running first though.
