Valve cover clearance with Hughes roller rockers

(I'd gotten those 1.7 roller rockers for free from a buddy when he had "reconfigured" his build, so I thought I'd try them) I don't think I'd have paid the $600 for a set of them new which was the going price from MP at the time) but it did make a little bit of difference in "get up and go"/// enough to notice at the time, but nothing "earth shattering".
