Yeah I’ll do that. I actually already bought some aluminum heads to throw on it.
If you're going to install aluminum heads, why are you worried about it? You're going to need all new rockers and pushrods anyway.

I was under the assumption I could use the originals until I researched a bit
That's another negatory, Good Buddy. The Aluminum heads will require a completely different valve train geometry and different rocker arms. I would suggest something like Harlan Sharp rollers. Then you will need an adjustable push rod to determine what the length should be. Search online for that procedure. It involves marking the valve tip with a sharpie, turning the engine and seeing where the rocker contacts the valve. Once you determine the correct push rod length, you will have order custom, hardened push rods. That could take a while.

Sorry, but them's the facts.

Yeah that’s what I’ve found. I have a flat tappet cam and lifters so can I use roller rockers?
Absolutely you can. There are many good roller rockers on the market. But there are also some lousy rockers out there, so don't just buy what's cheap. I went with Lunati roller rockers, but as I said, the Harlan Sharp rockers are good quality at a good price. Those have been around forever and have proven reliable.

Since you have a hydraulic cam, you will have to get a solid lifter to use the adjustable push rod. I've heard of people also disassembling a hydraulic lifter and putting washers in it for the same affect. My cam is a solid, flat tappet, so I was able to use a lifter as-is. Once you get the roller rockers, determine how high they sit for selecting valve covers.
