Cam Bearings..

I am about to take my home ported head over to the machine shop for decking, hardened seats, and cut for bigger valves. I was looking at those replacement cam bearings which feed oil to the upper half of the bearing instead of from the bottom. Was thinking of replacing them myself, has anyone replaced the 2.3 cam bearings themselves? I tried tapping the old ones out with a brass punch, but they didn't seem to move at all. Thoughts? Thanks

I’ve been looking at rebuilding an engine myself—got most everything, just need to find some affordable oversized pistons—but from what I’ve read, it’s not recommended that you attempt the bearings removal yourself.

Others might have personal experience with this. My thought is, have the machine shop do it.

^^^ Agree 100%

If not done correctly you risk bending the cam towers. Even a very very slight bend in the cam towers will result in the cam not rotating freely damaging both the cam and the new bearings.
