Make sure you have the heaters wired in parallel and feeding them with 240v.

A common mistake is to wire them in series or use only 1/2 the 240v circuit. Both sides of the hot legs are used for 240v. The common is NOT connected to the heaters. Were the heaters glowing red?

A heat sink is a good idea no mater what the amp rating of the SSR might be. You need to check the specs of your SSR. Some gain their rating by having a very large heat sink. Without it, it may be rated at 20A or less. You're drawing over 40A!
