A previous topic has sparked some interest for me to do a hybrid motor...so, after digging through the archives I found some great info on doing a flat tappet LA hybrid. I however want to do a roller version. I have an 86 roller LA motor. Does anybody know: will the stock Magnum valve train work in the roller LA? If I get Mag heads, can I use the Mag heads, can I use the Mag pushrods and roller lifters in the roller LA block? If so, are any mods necceassary or will the parts drop right in? It is enticing to bolt the better breathing and smaller chamber Mag heads on my lethargic 318 to wake it up....for dirt cheap! If anybody has done this, please. Please share info pics or whatever!! I really wanna try this!
