hi
just looking at the pic and it looks of front to rear to me ??
if so no machining is gona fix that , need a hole relocate ???

if i am wrong and it is side to side you can eliminate the .030 gaskets and just use the metal belly pan !
it will seal fine i have done it many times .
use a Small 1/6 bead of silicone around the port area on both sides and allow it to cure over night. make sure pan and head are oil free!
this will allow the intake to sit much further down in the valley so all holes line up !

what intake are you replacing ?





^^^^^^^ THIS ^^^^^^^^ Looking at the picture it gives the appearance of up and down but the manifold edge tells me you have the picture rotated !!!!!!!!!

Are these blocks and heads new to you ?

If this really is a sideways misalignment you have more than a bolt hole issue to contend with ... PORT MISALIGNMENT ...... CHAMBER TO BORE and with a 413 that could mean intake valves hitting the edge of the bore ????
