ROCKER ARM TO VALVE TIP CLEARANCE ON A FRESH REBUILD

2002 Ford F-150 • 4.2L 6 cylinder 2WD Manual • 202,000 miles

What is the recomended rocker arm to valve tip clearance on a 2002 F150 4.2L V6.
First I must tell you I have installed a Comp Cams camshaft, Comp Cams roller lifters and Harland Sharp 1.8 full roller rockers. The pushrods are stock legnth. With number 1 cylinder at TDC the clearance seems exssesive and the book I'm using has no info. I may have to grind down the pedestal where the rockers fulcrum rest on. The highest feeler guage I have is 0.024 in. And you can fit 2 of them in there. Please help me finish 'ole reliable correctly.

We wouldn't have any specs on a custom setup like that. I would thing the manufacturer or distributor would have that.
