The Fel-Pro 1612's work excellent for rpm heads and mp cast valve covers.
The big down side with them for me has been.......after they have been installed a while, when you remove the v/c, it usually tears the gasket, and you need to replace them.
I've had good results with the moroso gaskets on Indy heads using Indy v/c's, with studs and nylock nuts.
I squish them down a little and call it good.
I'm jealous of how clean that engine bay is!!!
Next engine you do an engine with Indy covers try a set of the Cometic rubber coated steel gaskets. The Cometic gaskets are a step or two better than the Moroso gaskets. I've thrown all my Moroso gaskets away and switched all of my engines over to the Cometic gaskets. Zero leaks even after having the covers on and off a bunch. And the Cometic gaskets will hold a bunch of pan vacuum.
