1.8 Ultra Light Rockers For Ls2

[sting ls2]

What kind of gains would i be looking at with this mod,possibly fit some comp918 valve springs at the same time.
I heard these ultra lights some times hit the inside of the rocker covers and the rockers covers have to be milled out a bit or hit the rocker covers with a grinder,any tuth to this rumour,or maybe use a spacer.also a price would be nice.

Usual power gain with standard cammed engines is around 10%.
Yes some of the late model valve covers have bigger boss's underneath that can cause interference with aftermarket rockers. Sometimes the rivetts holding the tin baffle on are not pressed down properly too. We have valve cover spacers available but you have to use longer plug leads as well.
Cheers.
