Nice, thank you!!
I also have a '75 360 sitting in a Winnebago, do you think those heads would be an improvement over the small port/valve '74 318? I plan on doing this home head porting and want the best bang for my bucks. If the 360 is still good that could be an option also but I don't mind running the 318. It's in a '74 power wagon so millage and power is what im looking for.
