What would be the purpose in that ? If you changed to like an LBZ you'd have to have the bridge and all.

jus thinkn that there might be a little restriction in the cali set up. not sure tho.

You need to be replacing your heads with federal heads...the intake runners are nothing compared to the heads.

But LBZ intake runners will flow more than LB7 ones
