How to install in intake?

Lay approx. a 1/4" bead on each end of the block,run it up the side of the head about 3/8" on both sides front and back. Then with a little blue silicon put a small amount around each water passage then lay your intake gasket ont the heads. then GENTLY lay your intake in place. Make sure you get it the right spot so you dont have to move it around too much and pull out the RTV.start the intake bolts by finger first. Use a little rtv on the threads to seal the bolts, and use a small (AN) style washer with the bolts tighten them in order starting in the middle and working your way to the ends. Let the truck set overnight so the RTV cures. As long as you mark the location of the rotor tip on your distributor and put the dist. back in the same way you can tune it by ear to get you by or you can purchase a timing light and set it right. change your oil when youre done cause you will get some antifreeze/water in the lifter valley when you pull the intake off.-Sorry SOOO long!

I searched engine& drive train and this forum. The information I found has me concerned…..I have a felpro 1205 gasket, is it ok to use? I’m putting on a Edelbrock intake and only want to do this once!
I plan on using ultra gray on the intake ends (in lieu of the rubber) and also on the bolts.
Can I use Teflon paste on the bolts?
I’ll probably find torque info in my shop manual or Google.
