If you like you can double check the clearance by assembling on piston in the motor with the head and a few valves. Turn the motor over by hand. Use marking dye or something, I don't know.
I just use some kids play putty like plasticine that you buy from BigW toy dept and make a disc on top of the piston - with the crank rod, piston, cams etc all dummy assembled, with 2nd hand bearings and head gasket (1 piston is all that is required). Turn the crank through 2 x full rotations - disassemble and see the depression left by the valve on the plastic putty. You will need to measure the clearance - NO LESS than 3mm.
All of these instructions are available from good hot rodding type books.
