NO! The Poly SS-X manifold (and valve covers) are true works of art… Vasquez took his creative brilliance and Pavlovich’s directions to the highest degree of fit and finish. We left room in the intake manifold to port and is why some of the bolt holes and bosses look like they were relieved-THEY ARE!!! Dave Antonucci just sent an update on his findings and photos of his Rat Rod with the new manifold installed… Even the Hot Heads 392 manifold by Vasquez has similar machining necessary at the factory and they use a button head bolt turned down to hold their manifold on with only 6 bolts per side and we have 8… Its all about the bigger ports… Vasquez however continues to remind me (yesterday again) that he highly recommends the head be port matched to the intake about one inch in… We realize guys who just want a
simple bolt-on can’t do that and performance will still be outstanding-its just that he’s extremely meticulous like Pavlovich… So the only porting on the manifold required is if you do a full port on the heads and we’ve left you plenty of meat to do that as opposed to other manifolds out there…

Subject: RE: New Poly Intake Recipients - CHIME IN!
Thanks for the info. Will any porting of the intake be necessary, or a process such as extrude hone I think it was called?
Bruce is starting with a stock 2bbl…stock exhaust manifolds and stock y pipe-doing a baseline pull… adding the new Poly SS-X Deep Freeze manifold-another pull… adding tti headers another pull… That will be our baseline… He then is building one of his MAX strokers and will
be testing that later in the winter… but his initial testing using the DEEP FREEZE coated intake should fairly well replicate what the average Poly owner can expect by bolting on this manifold… The significance of the Deep Freeze coatings options shouldn’t skew the numbers significantly and we have so few manifolds yet that we sent him the deep freeze one and the normal uncoated wind tunnels to long time patient contributors…
