Those heads have a smaller chamber than the 360 heads and will raise your compression. Since they are ported they should flow good enough. IMO, I would go with a bigger than stock cam to avoid pinging and putting that higher compression to good use.
The motor I'm putting these on has a small can the guy who built the motor kept asking what kind of carb and intake I was going to run he said he would tell the can grinder at launity to grind it to match
