If possible orient the heat sinks such that the fins are vertical. Then either let the heat sinks poke through the side of the chassis or drill a bunch of holes below the heat sink fins and above them for the air to flow through.

Modulus-86, 186, 286, & 686: 40-240W (8Ω) at <-120dB THD. HP-1: 3W/20Ω, -130dB THD, 128dB DNR.

Ideally I think you’d want to create a open air path for convection - usually with the fins of heat sinks oriented vertically. With high efficiency class D type amps such as Hypex modules, the thick extruded side panels of something like the DIY Audio store Slimlines work great, but amps like Toms, or the class A ACAs need either surface area exposed to free air, or some other creative heatsink /cooling mechanism with which to dissipate that thermal energy.

OK, I see Tom answered pretty much the same thing
you know I canít quit you, baby
