I have a set of Sportsman IIs going on a 350 - is the correct intake manifold a vortech or non-vortech?
They are 011250s - 64cc straight plug - not ported. They are going onto a 350 st bore with a TBD cam - all in a 3300 lb Nova for street use.

it would help if you posted the part numbers, but all world products sportsman II heads are none vortech heads.
world products dose make vortech heads, but it will be stamped right on the the heads ( vortech )
and i wish i could tell you just what intake will go good with those heads, but i would need to know the part number is to those heads, what cam you have or are going to use, and what motor as in , year and what it come out of?
the year wouldve helped as well, but if this motor is before 1986 i would use
edelbrock performer rpm/air gap
part# EDL-2601
if its 87 or newer part# EDL-2604
both are from summitracing.com
thats the best intake for your heads with the motor set up you have as there not much dont to it from what you posted.
this intake makes power from idle to 5,500rpm.
o ya and those are NOT vortech heads...

seem to be certain how the intake bolts on . The extra moderen vortec sort has bolts that are straight away up and down . On those intakes you may placed studs on your heads and drop the intake on , you cant try this on the Gen one million stuff . you have a ninety 9.999% risk that if its for a carburator this is going to artwork. The dip stick in undemanding terms affected the block and pan . each element else is the comparable on the carburated autos.
