Hey guys, I'm looking at puting a AMC 258 i6 / 4.2l out of an '83 vehicle into my '80 jeep. No biggie there. But I'm looking at possibly doing a few upgrades while I'm at it. One being a swap to a 4.0L head. There's a couple at my local bone yard to choose from. What i wa wondering is if i swap heads will i have to get different length pushrods? And ic so how would i determine what length i would need? Or is it just as simple as buying a set for the year of head i bought?
Are there any other concerns to concider? Like years to stay away from? Better years to get? Things like that. Thanks guys.
