Some one ask so I tried to explain in a PM. Rocker oiling

Bakerlite said

I've converted them to full time oiling as well as oiling up through a ball and ball pushrod like other makes do. You can block off the timed feeds from the cam if you use these methods and you don't have to mill the stud either.

That does work. The problem I had , Was with high lift roller cams and higher seat pressure springs, combined with the terrible pushrod angle due to relocated push rod holes in the head. The push rods gulled at the top. I realize a mild engine with standard style heads are easier and there are many other ways to oil the rockers .

This method my son uses learning from our engine build is the easiest and cheapest route for customer built engines requiring studs. Customers but not all pick or bring the parts for their engines. My son is only liable to oil the parts they choose. This is an across the board way to get oil up top without reinventing the wheel on every build.

He now has a lifter bore truing fixture for big and small block Chevy and mopars plus Hemi and Pontiac. We have some blocks here with oil problems due to lifter oil galley holes to low or oval in the block even with the new roller lifters on some big blocks. Also truing the bores helps oiling due to lifter holes being to ovaled and leaking past the side . Truing them really increases the HP putting the lifters all in the correct timed position. All his Engines stay together for complete seasons.

The track inspector for a local oval track who also is a parts supplier just told my son yesterday that one of his engines just broke the record lap time. Also 2nd and 3rd were cars with his engines. His race engines of all types already have very good reputations and bringing new customers from Diesels to Nitro

So that said I trust what he does.
