Adjustable Rockers looks like 2 types

Without going down a rabbit hole, take a couple off measure and compare critical points. If u can keep an eye out for another 8 of the bulky ones and replace. Or just run what u got.

I will do this for sure.

How many of each are there?

I would be curious and do a ratio test on my engine and if one gave higher lift I personally would run that on the intake side. The biggest problem with those rockers were the insides. We banana grooved the shafts years ago to keep them from gulding on the shafts. Find the spec and check the inside diameter. Have fun and good luck.

Good idea, I am hoping there is only 2 different types of rockers and there are 8 of one type and another 8 of the other type.

Funny you ask that question because I was just posting that I am hoping that there are 8 of each type.

That could actually be beneficial. If someone put 8 stock ones on the intake and 8 1.6s on the exhaust, for example. Depending on the camshaft grind, that could be adding a little power.

Looking through my photos the driver side looks like 4 of each, that’s good.
The passenger side picture I can see 5 good examples and 1 barely, and it looks like 3 of each.

The non 273 looks like Crane or maybe Isky. But not T/A.

Yes, the intakes rockers are offset on the TA's. Without the valve Trane, look for the intake pushrod slot being egg shaped.
