Yeah I might just go with the 1.6ers which will put me at .555/ .572 I called AFR about it this morning, and although the heads are made for up to .600 of lift, the tech said it would be wise to shim the valve springs for the 1.65 rockers. I'm a little too lazy for all of that.

I've decided to stick with my rockers. The consensus seems to be that the roller tips actually don't roll (which is proabably why they're wearing the way that they are) and are therefore not all that critical. The actual rollers themselves are in good shape so it will be fine.

I question this. My comp cams roller tips STILL roll after many years. There is something wrong here. Ok, think this--if the pin breaks that holds the roller tip, the roller tip will come out then the arm will come down on the retainer knocking the keepers out and dropping a valve. :barf:

I have seen this.

Damn you! You single handedly managed to make me spend $250 with one post.

Ahhh! Guess I'll be saving money in the long run though.

That's ok, I have some lifetime warranty 1.65 Harland Sharp rollers coming in the mail.

And I will now have .576 in, .594 ex lift :D Assuming my pushrods clear the heads and my valves clear the piston. When they get here I'll bust out the playdo and let yall know what's up. :thumbs_up:
