Mixing Hollow and Solid Push rods

This is actually a question directed at 286 Merc. I noticed an older thread where you said to be sure not to mix hollow and solid pushrods. Just so happens my engine has a new though incomplete set of 11 hollow rods, and the remaining stock solids. Engine is 292. Agreed it is not a very tidy setup, and one that I plan on changing, but what are the real downsides?

The lifters were designed in the "Y" for a smooth tipped solid type, a hollow will cause wear pattern issues, and you do not want to be changing lifter in a Y at all and this is because unlike a hydraulic lifter, in a Yblock, you have to remove the camshaft to change a damaged lifter because lifters are inserted from underside in a Yblock. I wouldn't want the unneccesary job if i could avoid it for sure for sure....Janet
