Would pushrod length change automatically because of using 1.8 instead of 1.7 rockers..??

I'm going to say "not enough to matter" but perhaps someone who has tried it can chime in. You should probably check anyway.

You should also pay attention to the wipe pattern with the new rockers. You may need to shim them to get a good wipe pattern.

They shouldn't require longer pushrods. The new rockers increase the ratio by moving the point the pushrod touches the rocker closer to the fulcrum. The rockers are designed to be a bolt on application.

Depends on current rockers vs. new rockers. For example, the Crane kit comes with 7.250 pushrods. If the pushrod cup is moved to obtain the higher ratio, you need to verify pushrod length and it is the pushrod cup that is altered to obtain 1.8. Bottom line, verify your length.

Exactly my thoughts. Shouldn't need different pushrods but maybe I'm just crazy.

There shouldn't be a significant change unless the rocker company requires it i.e. Comp and Crane. Typically the pushrod length is unchanged.
