Do Not use sealer on intake casket.
Sealers can cause More problems... RTV Silicon
will cause More problems here.
FEL-PRO MS90563? is made w/ a groove between coolant and #4 and sealers can defeat that groove.
If you really want this... Paint High Tack or Super 300 only a bit around coolant port.
Head intake bolts needs correct Torque because head and intake moves as engine gets hot and cools down. Too loose and the bolts
will back out over time. Too tight and small bolts or intake can break. Need Clean Dry treads to get proper torque.
