383 for a 67 cuda

What is your budget for this engine?
My budget for the whole car is about 15k to 20k. I was going to put about 7k to 10k in the engine, trans, and rear end.

The same crap... 8) I have "516" casting heads, which were used on alot of 413 passenger cars.
I checked the cylinder heads I have for the casting number and they were 2206324. After looking around it shows them as 1961-1962 Intake 2.08 Exhaust 1.60.

Can the heads be opened up and if so by how much?
