Would these heads be good on a mild 383? I'm thinking KB flat tops, XE274 cam, stock rockers, Performer RPM intake and headers. Originally I was wanting to do a budget build, but I might want to get these if anything to use on another project at some point. I want to use the parts I listed to keep my budget in check. I just thought I was going to have to spend money to have the 906's rebuilt anyway so I might as well get something I can use somewhere else if I want.

Would anyone also know what my Compression Ratio would be? Not sure of the head gasket thickness yet, and as far as I know it will have a stock deck height (if anyone could recommend a measurement to mill the block would help). Thanks
