TF 190 Heads

I appreciate your consideration for my time. Thank you.
I can make the corrections for just about any rocker, and thankfully, the TF heads don't need very much. However, the PRW rockers fit the heads very well, and allow pushrod oiling for Magnum applications. I wouldn't rush to do pushrod oiling on an LA block because the lifters could push too much oil to the top end, unless the lifter bores were bushed.
I have the Hughes 1.6: 1 aluminum rockers on my cast iron heads. I was wondering if you had any experience with these rockers on aluminum heads? I've heard several engine builders talking about comp, PRW, Harland Sharp, ect..
I was wondering about geometry as they seemed to have bolted right on stock heads without any need for correction..
I guess what I'm asking is if you think they would be worth trying on the new trick flow heads or should I just add the cost of those as well? And like stated before thank you for your time if you get a chance...
