To find out the thickness of gasket you need.
You need to know how much the machinist removed from the head.
Go to:
Performance Parts Aftermarket and Racing
Get the # when the tone asks for an extension..., dial 103.
You'll be speaking to dave. He can get you the gasket that you need.
With the info from the machinist, he'll go to a chart that will tell him
the thickness required.
I would seriously go beaded.
A MACHINED block. Not just a 2x4 and if you didn't sand on it for days.
You didn't do any good nor did you hurt anything. So long as you cleaned it out very very well.
You'll also be wanting arp studs or bolts.
You're going to need a volt meter and a torque wrench.
All of the seals you destroy during the tear down, you want to order them as soon as you have enough to constitute a real parts order.
I used a 2.mm stopper HKS. It's bloody beautiful.
You'll feel much better once you press the head down and retorque
the head to 80lbs. You'll know the difference and quick.
DO it right. Do it once.
