forgot thread seal on manifold

Another thread reminded me I had forgot thread sealant on the manifold bolts. this is a victor jr manifold mating to Aluminum heads and GM 3970010 block; with arp stainless bolts. gaskets are felpro with the silicon beads, plus some orange rtv I put on myself. I did an otherwise good job...

Is it a bad idea to unscrew the bolts and leave the manifold on? Either by taking one bolt out, sealant it, then put it back in, or take them all out gently, slap the sealant on and screw them back in the correct order? either way it seems like it might disturb the gaskets, sorta like head gaskets that only like to be torqued once...what would you do? thanks

i always use plumbers pipe thread dope on head bolts and sometimes intake bolts

not a huge deal on intakes but on the v-8s and 4.3L and such oil does like to travel up the intake blts andpuddle on the intake

but not always

you could pull each one and do it and be ok on most engines

only the middle ones do it, the outer end ones are in blind dry holes on most engines.

good luck

Like Fast68 said, just pull and seal one at a time and you will have no problems.
