Flow Numbers? Seems like a lot for a 243 with stock valves IMO

Do you have a cam in mind? Blind flow data does not really provide any actual information or context unless we also have a camshaft in the equation.

Thanks for the info.

What is the intake and exhaust port sizing?

Curious about the intake/exhaust port sizing as well. Also, is the price listed on your website for a pair of new factory castings, seasoned cores, or customer supplied castings?
