Handling a head with half the valves sticking out is more risk than I'm willing to take. I'm more comfortable working alone without a hoist. <-- that's an opinion, not advice.
FWIW the OM603 addresses this issue - the cam towers cover head bolts so the cam has to go on last. <-- that's a fact however irrelevant
Might be worth asking the machinist what torque he/she used on the cam tower bolts. Should be reasonably fresh in his/her mind.
