Douglas,
The Joe Deppe cylinder head is an older design than Mikes head.
Mike's is better flowing & better quality.
The Deppe head has square intake ports so you need to make square tubing.
Mikes intake & exhaust ports are round so it would be easier to fab an intake & exhaust manifold.
What did you mean by you do not have a register Mike's cyl head?
You have seen his website... correct?
Regards,
Hank
