Sorry to disagree, but I had very good luck with this method for many years on many vehicles even on ported intake tracts. I didn't have to change gasket on mine VX yet possibly because I re-torqued down most of the bolts after break in period. I assume that new VX gasket has self adhesive coating on it to keep it in place during installation, this adhesive/sealing substance may not be as effective as gasket cement which would explain the need to do it the second time within 20k on Andys454 wife's Trooper.
FelPro has put out some publications in the past that deal with this subject.
