Carb Heat and Fuel Line Holes

Howdy Everyone. My plan is to use the YIO360-A1B6 engine and a Hartzell CS prop from Vans in my -7. Is the as drawn location for the cabin heat hole in the firewall, drawing 19, a good location or should I relocate it? Also it is not clear to me where to locate the hole for the fuel line to pass on the firewall.

Any guidance is appreciated.
