Harland sharp roller rockers

[jetmech]

Just a heads up, I TRIED to install a set of harland sharp roller rockers in my 4.8L and sure enough they didn't fit under the valve covers. That said, I can gaurantee they won't clear in a 5.3L either. To make matters worse, because the roller rockers are so damn big, you can't even use valve cover spacers with them either as the roller rockers sit EXTREMELY close to the top of the cylinder head wall where the lip of the spacer would mate to. The only method of achieving proper clearance would probably be to use aftermarket valve covers which I discovered are expensive. So does anyone know who makes higher ratio (Preferably 1.8:1) roller rockers that WILL fit under factory valve covers?

Go with the scorpions. They r a direct bolt in kit and they are about 350 bux. Ive heard and read a lot of good things about them also.

stockers FTW, good enough for the LS7 good enough for rest of gm motors

Crane part number 144759-16. Gold 1.8 ratio rockers, they fit under the stock valve covers without any modification.

1.8 rockers are a good deal for people like me that want a little extra for a little work.....yes,buying them new is not cost effective but picking up a set for 200.00 or less isnt bad and in my case would give me 588 lift versus 535...just my opinion.Are you gonna sell those rockers?....or trade....?

already returned the rockers

will the scorpion rockers trigger the knock sensor? There isn't much info on their website. Crane cams' website said their rockers won't trigger the knock sensor. Any thoughts?
