Wrong heads for a 273
It would be interesting to know what the limit the 273 bore and stroke has as far as port flow. It can only use so many cfm and there's no reason to have more that can't be used. You would need to run a 273 at 8000+ rpm to use all that flow. All the manufacturers have done it. Boss 302, 302 Z28 Chevy, etc. If I ever have a reason to pull my heads I hope to flow them just to see what they will do.
