Just measure it, why speculate?



Sorry, but I was not in my garage, when wrote that question and my garage is over 35 miles from my office, and I needed a honest answer because from Hughes Engines they said maximum lift with stock guide height is 0.450". More lift would require shortening the valve guides. I thought it's a little bit low, because I have even earlier used cams up to 0.507 without shortening guides.
