Engine Bent Valves! Rebuilding. General Questions.

So my timing chain snapped and every single one of my valves got bent. I pulled both heads and rebuilt the valvetrain. I have AFR 185cc "Renegade" aluminum heads. I am using head gasket Felpro #1011-2. Should I use permatex on the head gasket or just install it clean? I know the torque spec is 100 ft/lbs and I got the sequence but it seems like the water jackets should be sealed with RTV. I'll probably have a few more questions as I go but for now that's what I need to know. Thanks all.

I got it all back together. I was having a hard time setting the valve lash but I got it done. I turned the motor by hand to check piston/valve clearance. Everything seems ok. Now I have no spark. The MSD box and the coil are both good. It has to be the TFI module or ECM.


What hole is this!?!

Are you sure the torque setting on the head bolts is 100 ft/lbs? I had a recent issue with this. The correct torque spec was actually 70 for my bolts. (ARP set: 1/2 inch heads, 7/16 bolt)
Yes the torques setting is 70 ft/lb. The 351W is 100, the AFR guy was confused. It was the TFI module that was causing the no spark condition. The car is up and running but the rocker arms aren't tight enough and they are ticking pretty loud. I'm gonna adjust them today.
