Aluminum cylinder heads
I've used these roller rockers that Mancini sells.They are manufactured by Harland Sharp for Mancini.They are not the needle bearing type but are the bushed type of rocker. Used these on a few engines and they work good. You can order them with or without the billet holdowns. I prefer the billet holdowns. As far as push rods I use Smith Brothers. They have always worked great for me and they make a good pushrod.
