Ok I have the a 1986 350 L98 with the
462624 Iron Heads on it right now. I am looking to swap 113s Al castings on (I already have a pair)

I am just looking to see :

A) Anyone done this? Who are you?

B) What's involved?
You see I am putting on a whole new high flow LTR system with a new intake base and these heads. This is going on an engine that is currently the stock 350 and when it goes kaput will be built into a 383. Thus I am not going to swap a cam in. Basically what I really really need to know. Is can I use the same pushrods? Will the lenghts be different, do I need customs. (I will be going to 1.6 roller tip rockers btw but that shouldn't matter)

I just am doing this thissummer and want to have all the logistics set so I can do it and drive it after a mostly problem free install. Thanks guys! I haven't been able to find anyone on this!
