I am having this same sound and wondering what that is. It only comes on after the engine is just turned off and is about 5 sec. on the passengers side of the engine. I did have the heads milled down to 63 cc from 65 and not the intake. Could it be pressure being released after the engine is turned off and a bad seal from the intake not seated and leaking from the intake gasket?

Will do a compression test tomorrow.

I discovered that the pressure release sound after shutting of the engine was actually the back plate gasket on my water pump was leaking. Problem solved.
