Default What heatsink for Holtons lateral amp?

Hi!
I built Holtons lateral amp with +-65V voltage rails (so something like 160W/module) and got a 0,4K/W heatsink. Will it be ok to mount both modules on this heatsink or is it too small?

Default my calculations...don't know if they are right...

ok... assuming 320W power output and 30% additional power that goes just into heat, about 100W (96W) of heat is produced.
with my heatsink (0.4 K/W) i have a teperature raise of about 40.
Ambienttemperature is 20C-25C (on a hot day where I live).
So the amp temperature will be something from 60C to 65C at full power?
The outputdevices are rated at 55W/pcs at 65C.
Four devices in the output produce 160W, every device has to provide 40W.
So I think the heatsink will do it...but not sure if my calculations are right...
Please correct me!
Konstantin
