Default LS Hydraulic Roller Lifters

I bought these as a replacement for my L98. They look identical to the stock lifters except the front and rear area above the roller is not slanted up like the stock ones. I could see were maybe with an aggressive cam the lobe may encounter the body of the lifter as it is moving across the roller. Has anyone had any problem with this?

The ones I bought are from Summitt and are part number NAL-12499225.

Thanks

Those are the lifters used in the LS7. Shouldn't be a problem with aggressive lobes.

Just for general information my new build has the LS-7 lifters in my L98. We ran it on the engine dyno this past week and took it up to 6800rpm as that is when the power started to nose over. I had the pre-load set at one full turn. No problem at all running the LS-7 lifters in a L-98.
