Depends on how many miles, but you should be fine. I've done a set of bolts on a 99 engine with 125K on it and had no ill issues. Rev's to 7K on the daily according to the owner of that car.

Don't forget pushrods... The stockers aren't that stout.

Sorry to bring up an old thread, but I'm doing some research on mild higher rpm builds. I'm looking for a build that will get me to 7000 safely all day. This is the information I've gathered so far from the discussion:

stronger pushrods (Chromoly) - to handle the repeated abuse
high tensile strength rod bolts - to handle the increased forces during piston directional speed changes
high rate springs (preferrably single) - to decrease valve float at higher RPMs

Someone mentioned PAC 1518 springs. Can anyone else recommend other good low lift high RPM valve springs?

My goal is to set the limiter to maybe 7000, and shift at around 6800, but I'd like piece of mind in case i'm ever forced to bounce off the limiter for more than a second.
