A/C brackets with headers

[canso]

I searched the A/C brackets but could not find the info I needed. I want to put a set of headers on my small block. Does someone sell a different A/C bracket that normally bolts to the exhaust manifold. I could shim it out but I thought I would buy the correct one if there is one available. I have tall valve covers and my bracket that bolts on the back of the comp. to the bracket on the intake will hit the valve covers. Do they make a taller one to bolt to the intake or do I need to build one. Thanks
