small block heads, 4027596 casting # any good??

I don’t have to explain anything to you

Is that because you can't......

I don’t care.

Obviously you do care as you chase me around on every thread.

trying to prove some silly philosophy that we should start with outdated, used up castings to prove we know something. There is no reason to do what you claim you do, unless you love mental masturbation and working to do work.

What do you care what I do with my junk.

Your premise is stupid. And faulty.

Go fast with junk is stupid......
