Solid roller lifters...

Everyone has there own way of going about things......
And, if you’re having good luck doing something a certain way...... I’m all for continuing on with that process.

That being said....... I don’t like to use “tighter” lsa cams when the duration starts to get long...... and mufflers will be utilized.

The added overlap often results in more reversion at low engine speeds, which can be a challenge to tune for.

A quick test to see how much of an issue this might be is to remove the mufflers and see if the drivability improves.

Oh, and I spoke to Brad from BAM about the axle oiling.
As it turns out the oil holes just above the axles are the “auxiliary” oiling holes, and that there is a small hole edm’d from the cavity in the body to the area just above the wheel.
It’s there in the drawing I posted if you blow it way up and know to look for it.
