I believe its the hydraulic roller, if you need help deciding why not give KRC or SOCALDAKOTAS a call? they should be able to help you to decide, and get you exactly what you need!

Mopar began phasing in roller cams in 1985, and had covered the line with all hydraulic rollers by 1987.

I did some research on this not too long ago. You can use those rocker arms, but you also need a conversion kit to make them fit the stock heads. And they won't fit under stock valve covers, so you have to buy a taller set. Push rods will be a custom size. So you'll have to assemble everything, use an adjustable push rod to check fit, and then order the size you need.
By the time you add up all the parts, it's easier and cheaper to buy a set of steel Crowers from somebody like KRC and simply bolt them on.
The other issue is ratio. Stock is 1.6. Steel Crowers are 1.7. That's where the performance advantage is, the increased valve lift. Adding a big alum roller with the same ratio will gain you exactly nothing. Your wallet will be a lot lighter, so that may be an advantage.
