Anyone use an engine lift plate anymore on aluminum intakes?

I have done it, too, on a 340 with an RPM performer with no problem! the advise on good bolts that are long enough to use all the threads in the intake is the best advise. I use bolts that are 4 inches with a jamb nut. I tighten the bolt till it bottoms, them tighten the jamb nuts down onto the plate. Use a load leveler to lessen the stress and have better control.
