stock rockers would work fine. Going to a roller rocker is a minimal gain in a setup like that. I got a sweet deal on my crane 1.6 rrs and my oem rockers were worn beyond spec, that was my only reason for changing them out.

Got gt40p heads with 3k miles on them, new valve guides, valve stem seals, .560 lift springs, titanium springs and retainers, crane roller rockers, shims, pushrods and all for 480 shipped to my door.

oh wow thats nice man good for you im paying 150 tomorrow for a set of gt40p heads i just gotta get them machined and pressure tested and valve job for another 150 or so. So 300 give or take a little and then cobra intake for 200. so 500 For what i hope is gonna be
60 rwhp Plus i gotta get a cam.... Not sure what im going to do there prob just a E cam i think.... I should expect at least a 60 hp gain no?

Don't do it, stick with the stock cam and get 1.7 rockers.

I think you would be more happy with a different cam setup. The stock cams are known to perform well.

I like trick flow series cams as they are a lot newer grindings than those dinosaur alphabet cams, but it's still an Off the shelf cam.

I think you would be better off sticking with the stock cam at this point.
