The only thing you need are the aluminum valve covers if you don't have them.  1.7's will not clear the stamped steel covers

Yep. If he's got the stock HO aluminum valve covers you should just have to remove the baffle on the passenger side cover. Should work fine.

If you added 1.7s rockers with a b-cam what would the lift be with on the cam?

Has anyone timed the ho cam with 1.7's and checked the clearance on so pistons. Would like to use that combo, driven hard. I believe nominal clearance is .080" intake and .100" exhaust. Would that much be necessary or would the high mileage e7 springs and roller lifters need to be replaced?
