Not really.... the cam is considerably harder than stock and these blanks and cams tend not to wipe on the bigger "stage X" cams.... that said, there are obviously no guarantees. The system is obviously flawed from the onset. Guaranteed not to wipe comes with the Ferrea solid roller rocker, but that's not for everyone.... These intake cams will improve the durability but not cure the inherent design flaw in the head...
I've read a number of these wiped cam threads and I thought the consensus was we didn't know what the cause is. But you seem to be saying here that it's a defective head design. If so, what's the defect. And wouldn't this mean that all 2zz engines, or at least all of them in our cars, will fail (all have the same head design)?
The last post mentioned lack of zinc in the newer motor oils. I thought this was only a problem for older cars designed to run on non-synthetic dino oil?
