Just curious what I could safely run for lift on stock L92 rocker arms. The new cam I bought is .624/.610, wondering if its going to be an issue down the road?

all I would need to do to save the guides is aftermarket rockers right?

And the beat goes on...
dime, if your valvetrain parts are correctly matched, the lift you mentioned will work with stock rockers. Not everyone matches valvetrain parts correctly, however.

I had a 233/239 .600" lift cam and did around 20 1/4 mile passes shifting at 7100rpm, at least 6hrs worth of WOT road racing, and 20K miles total (street/racing etc) with zero issues on the stock rockers. The engine supposedly had 23K miles when I installed the cam and AFR 205's. I would spend the money and at least get them rebuilt for peace of mind.

"...and more spring to handle the heavier (higher MOI) aftermarker rockers, and stiffer pushrods to handle the extra inertia loads from the heavier rockers and the stronger, heavier springs.
And the beat goes on..."
Yep, sound advice.

alright, well the PR and springs are already taken care of so i guess ill just roll with the stockers for a while and consider upgrading later. Thanks everyone for the input.
