I have a question on cylinder heads. This is the current rule on heads:
Section 607
Heads
§607.1 Types Permitted. Heads must be stock for the make and model of the vehicle, cast iron only.
My car is a 1980 Buick Regal. Am I allowed to run a set of 462 casting heads?
Yes you can, it is a chev OEM part
Hey Rob,

The Captain is correct. No runner machining. phil
Thanks.
I guess that makes sense, since they allow 350's in GM Metric chassis.
