bb chevy tapered exhaust manifold spacer
 

Hi all.
I need to get my two BB chevy
motors closer together, the only thing stopping me is the stellings headers are too close.
I need a tapered exhaust manifold spacer thats thin at the top and thicker at the base to get those headers to lean inwards a bit. there is enough room with the valve cover in place.
I see Hardin marine do a fixed thickness spacer that maybe
I could get machined but has anybody had this problem, and is their a supplier out their who lists such an item.

Thanks.

You could probably get one from CMI

I had mine made 3/4" top 3/8" bottom to kick my headers out from valve covers. The spacers you can buy have oval holes. Your headers are round you need to match the gaskets.
