> M-9424-A351 right out of the FRPP book. For use with 9.200 deck
> block and Yates M-6049-C3L heads.Over the years, Ford listed the M-9424-A351 part number in the Motorsport
catalog for three different intake manifolds. The first was for a C302
head on a 9.5" deck block. The second was for a Yates C3L head on a 9.5"
deck block and the third was for a Yates C3L head on a 9.2" deck block.
The C302 version of the intake is, by far, the most popular. All three
intakes were similar in appearance: tall single plane air gap intake
made by Roush. The rear end seal rail shape should match a 351W block,
not a 351C block (the Windsor is an outtie and the Cleveland is an innie)
but the intake does not have an integral thermostat housing like most
351W intakes.

Be aware the M-9424-A351 (for 9.5" deck) and M-9424-B351 (for 9.2" deck)
share the same basic casting and differ only by finish machining (location
of bolt holes, thickness of intake gasket flanges, and rear seal shape).
It is possible to make an A351 into a B351 by milling the cylinder head
to intake manifold flanges (you also have to mill the bottom of the end
seal rails), trimming the rear end seal rail (only if running on a 351C
block), and elongating the bolt holes. It is not uncommon to see an A351
converted after-the-fact into a B351. Lots of B351's out there that are
stamped as A351's. If you think you'll ever be stepping up to a Motorsport,
Dart, or Fontana race block you can just leave the rear seal overhang in
place. It'll seal fine against a 351C block and is required for the race
blocks.
If you have pictures of the intake, I can positively identify it.
I have both an A351 and a B351 here. I can also verify whether it
matches C302 or C3L heads if make a template of the ports and bolt
holes.
> hoping to buy a set of 302 c svo heads for a cleveland block
Great heads. Be aware these can be set up for either Cleveland (dry
manifold) or Windsor (wet manifold). You can convert between the two
by swapping the appropriate aluminum NPT plugs around in the head.
