Check all your bolts are tight, head bolts and exhaust.

What fuel/oil ratio are you using? 32:1 is pretty standard, even for breaking in the motor.
Pull the head and check the cylinder and head mating surfaces for flatness. 320 grit sandpaper on a piece of glass works good to true them up.
Aluminum or copper head gasket? Aluminum is use once and toss. Copper can be used a few times.
Torque the head to 12 lbs/ft. or 144 lbs/in. Get to full torque in 4 or 5 steps. Torque in an X pattern to avoid warping the head.

This guy was a "one and done" type of member/poster...He posted this and never came back in three months now.

I will be locking this thread now since the OP hasn't shown any interest in his own question being answered.
