hi,
i thought i had a i/e manifold for a 235 but i may be for a different motor. the casting #s are exhaust 9836988, intake 3836527. the ports line up on the head of my 235 but the spacing of the studs on the heat exchange is off. so a 235 heat exchange gasket does not work. the 235 studs are 2 1/8" apart while the mystery manifold has a stud spacing of 2.5". i found this out after i paid to have the nmystery manifold milled flat. i'd like to use the mystery manifold if i can find the right heat exchange gasket.
