dumb question about guide plates

[wichitacorvette]

Ok, im trying to install my guide plates but nowhere do i see how to correct the gap that is created my putting in the plates? there is a gap between the rocker arm and the pushrod/valve....... do u have to get bigger pushrods? if so, what size?

You can't just "bolt in" guide plates - you have to have the stud bosses machined down to compensate for the thickness of the guide plates and to maintain the rocker arm geometry, and drilled & tapped to accept the hex-based screw-in rocker studs that bolt the plates down in place. Once that's done and the heads are reassembled, you'll need new hardened pushrods to go with the plates; using stock non-hardened pushrods with guide plates will destroy the pushrods.
