I am using a TSP magic stick 3 cam, and I plan on purchasing a set of ETP 215 heads. I would like to have between 11:1 and 11.5:1 compression. What are the best options to go with as far as which valve springs, combustion chamber size, etc.? Also i believe that they are 11* standard instead of the normal 15*, am I right? What pushrods, head bolts, and gaskets would I need with an MS3 and the ET 215 heads?

You'll need to upgrade to .650" springs, get 60cc chambers, and .045 gaskets. This will make 11:5:1 compression. The heads are 11*. Pushrod legnth will be around 8.100", but you will need to verify with a adjustable pushrod legnth checker to make sure. ARP head studs will be the best for clamping down th eheads. Cometic makes the .045" gasket.

I thought their springs were good to .675"? The upgrades i was to understand was for their 15 degree ported stock castings. Maybe im wrong.

ETP uses Crane dual springs rated to .625 lift. The next upgrade is Comp. 977 dual springs rated to .650 lift.

I thought I had seen .650", but they list .650" as an option in the 11* section, so I'm unshure.

Will the stock crane duals be enough for the MS3?

I'll assume that the stock ones are 832's. If you shim them, you can get .650" lift out of them, but you will loose some height which could put you closer to coil bind. I'd personally have them install some PRC duals or the Patriots.
