NO MORE CAM BEARING ISSUES
We've found that almost all issues related to camshafts being too tight in the bearings are caused by burrs in the cam tunnel which were caused by the original bearing installation at the factory. This is especially true with split cam bearings like an LS or late model Hemi. In our shop, before the block goes in the hot tank, we use a bore polishing flap wheel that's smaller than the cam bore to very carefully just take the burrs off the big gouges. After that we use a dingle ball hone on a long extension and use honing oil to thoroughly deburr the cam tunnel bores. We started this process on LS Chevrolet's, but have since been doing it on all blocks and haven't had one go tight yet. This includes BB Chryslers! As a side note, LS Chevrolets usually have a giant burr at the opening of the cam bearing oil hole. This can be removed with a scrapper knife before running the dingle ball hone through. Now that everything is nicely deburred, those pieces of fractured metal from the burr won't go through your fresh bearings.

QUICK INSTALL TOOL
Yes it's great to have the proper tools to install a press-fit pick-up tube onto your new oil pump. There are times when you may be helping someone in their shop and you need to improvise a quick tool to get this job done. With two simple cuts with a metal saw, a piece of scrap steel pipe can be made into a driver to finish the job. If it wants to open up, just clamp it on with a vise-grips.

INEXPENSIVE T-HANDLE BOLTS
For 7/16” holes, take a 7/16” rocker arm stud, weld a metal pin at 90¨ on end and it becomes a T-Handle. Make 2 of them, this way you don’t need a wrench to take a lift chain off of an engine block. For ½” bolt holes you can do the same, but with a ½” rocker arm studs. The integral hex on the stud makes it safe and strong.

Mounting certain heads in a seat and guide machine can be difficult.
This is especially true if the heads are uneven or the head bolt holes aren't at the
same height. I have a few pieces that came with the machine but they
don't solve all the problems. I have several different length bolts and
nuts that I use as adjustable stands. They fit inside the head bolt
holes and can be adjusted by turning the nut. I ground all the marks off
the top of the bolts so it would be smooth. I keep them in my tool box
next to the machine for easy access.
