im pretty sure edelbrocks spec is only 15 lbs or so, its not very much at all.

do them till they r tight and then about another 1/2-3/4 of a turn. and ALWAYS start in the middle and work your way out on an aluminum intake. goo luck

i would go no more than 25, it;s not like your holding down the pistons or something. it just lets in air. as long as it seats and seals correct you should be ok. i used 14-lbs on the vortec and they only use 8 bolts, none on the center of the manifold. that was over 2yrs ago.
