What are dimensions on the factory valve guide? I Bought this set of heads and was told they had already had a valve job done when they were machined for 1.94" intake valves, guide plates and screw in studs.

It looks like the guides are freshly machined as are the the rocker arm stud location. Does it look like I gained any more clearance?

How does everything look? I am hoping I won't need anymore machine work to get ~.500" lift. (Using the appropriate springs)

 

Nothing? Somebody has to know what they looked like from the factory!

 

you may have to wait until the weekend people are here. they know a lot about the heads.
what heads are they? the number? the size?

 

My bad... I guess there are a bunch of other threads here

They definately '081 heads. As far as I know they still have 58cc combustion chambers. You have replied on the other thread concerning these particular heads, if the additional pictures or info can help:
