heads......problem
« on: February 15, 2011, 07:00:38 PM »
i got my EQheads in (ch350e ) .i had a edelbrock performer intake  to go with them but the heads runners are larger than the intakes ..........my question is do anyone know of a dual plane intake with large runners to fit pre 86 style intakes .(12) bolts ...........i brought the heads  with this pattern because i figured the intake would fit ...

that intake should fit those heads.
try a dry fit with the intake gaskets.
also how thick are your head gaskets?

NO!  The CH350E heads, these (right?), are a vortec port with an early style bolt pattern.  The only intake that will fit that port close enough is a raised runner intake (which are only available in single plane high rise configuration).  If you grind your 2101, you will find that you run out of material at the top of the runner before a match is met.  If you REALLY want to use that intake on those heads you're going to have to weld material on top of each intake runner, machine the mating surface flat, then port match.

Confirm what I just said, use a gasket as a template to gauge how much material you would need to remove before you whip out the grinder.

Did you check for yourself about being able to port match the 2101?  Don't put it past me to be completely wrong.  Do this before chasing down another intake.

Also, definitely contact EQ and see what intake they intend for these heads, and report back.

Where is the mis-match...on the top? I saw the Vortec combustion chamber, but didn't recall seeing anything about a Vortec intake port size. How far off & where is the problem? Is the head port larger than the intake port in every direction...as in "There would not be an obstruction of flow going from the carb toward the intake valve?" Lorne

from your last question;
if your intake runners are larger than you heads in any direction I would think that this would create a turbulence problem.

This makes sense as long as the 2101 has enough surface area for a tight air seal.
your heads are designed to make an unmatched intake work with the vortech design which has taller runners.
I would not order another intake without talking to some at enginequest and getting their recommendation
With heads you have, based on what they are designed to do, I would expect the 2101 to work.
