Jesus, you yourself said the heads like that would be UBER expensive.
So now you want me to think that you’d tell a customer to spend Super Stock money for cast iron heads when a decent prepped Edelbrock head would do at LEAST that good for way less than half the cost.
But, nooooo, you’d tell them that’s what you need. Hell, you could do a valve job to a W2 head and it would at LEAST make the power of the heads used in the article.
Unreal.
