heres what I have:
1969 350 block, 60 over. vortec heads with air gap manifold, stock distributor with crane xri upgrade.

the hole in the manifold is too big. bought mr gasket shim/bushing kit and I still have about .069 too much gap.

bushing OD 1.374, hole is 1.443.

what are my options?

I tried searching on multiple forums to find a solution any help is appreciated.[/align]
