Head Gaskets

Head Gaskets

I believe Fel Pro, Victor Reinz and Cometic make compatible headgaskets.
Ford and Fel Pro list specific head gaskets for high port heads. Victor
Reinz lists Windsor headgaskets when running Windsor block with high port
heads and Cleveland headgaskets when running a Cleveland block.

The old Ford Motorsport headgaskets were Fel Pros. The part numbers below
are likely obsolete but included for completeness.

M-6051-A331: Blue Fel Pro headgaskets for A3/B351/C302 heads on a Windsor
block. Does not have the round water transfer hole required for a
Cleveland block, otherwise same as A341. For 4.0″ bore (and likely
overbores up to 4.060″). Solid metallic core with wire encased combustion
seal for competition application. Surfaces are coated with Teflon. Do
not use sealer. Can be used with iron Cleveland heads.

M-6051-A341: Blue Fel Pro headgaskets for A3/B351/C302 heads on a Cleveland
block. Has the one round water transfer hole required for a Cleveland block,
otherwise same as A331. For 4.0″ bore (and likely overbores up to 4.060″).
Solid metallic core with wire encased combustion seal for competition
application. Surfaces are coated with Teflon. Do not use sealer. Can be
used with iron Cleveland heads.

M-6051-B331: For A3/B351/C302 or iron Cleveland heads on Windsor block.
Same as M-6051-A341 except has bifurcated (enlarged dual) coolant transfer
holes added for improved cooling and upper front coolant hole deleted so
Cleveland or A3/B351/C302 heads can be used on Windsor block.

M-6051-B341: Same as B331 but for blocks bored to up to 4.125″ (Fontana,
Dart, or Ford Motorsport race blocks). Bore flange valve pockets have been
added to unshroud intake and exhaust valves. Unique right and left hand
gaskets.

Note: Both B331 and B341 can be used on Cleveland blocks if modified per
supplied instructions.

For C302B heads on a Fontana block, Fontana lists Fel Pro p/n 1021 for up
to 4.1″ bore. This should probably be for less than 4.1″ bore as they were
too small a bore for my 4.1″ bore Fontana block which required the left and
right-handed gaskets (Fel Pro p/n 1022 and 1023).
