Lifter Bore Help

[hilandr452]

Howdy folks,

It's been awhile, but I'm finally rebuilding the 454 for my Longhorn. I removed the engine in the fall last year and just now have the parts for it. The engine only had 15000 miles on it and the cam went poopoo. Serves me right for installing someone else's build.

I'm going with the performer series cam, lifters, double roller timing chain, performer manifold, and 1406 performer square bore carb. Sealed power moly rings and rod/crank bearings. Also re-seating all the valves and changing the springs and seals in the heads.

Here's the issue, A few of the lifter bore holes are damaged. I think this is why the cam failed, lifters may not have been spinning like they should. I was also failing to use oil with zinc additive. (live and learn and all that...)I am using one of the used lifters that wasn't damaged to gauge proper fit and I have two which are too tight.

Is there a tool out there that buffs the bore a little for a better fit? I don't want to mess them up any more than they already are. Any helpful comments will be appreciated.

Dan
