Picking up a 2014 5.7 in a few days...
So what does everyone think about having the heads cleaned up and a valve job done? I've heard the earlier Hemis had valve seat failures, what did they do to fix them on the newer ones? Will I need new valve seats if I want a valve job? Or is it even worth it on a 140k-mile engine in the first place? I plan to get these heads washed anyway there was a lot of dirt that fell into the rocker area when it was being taken apart and as you can see in the pics the chambers and ports are pretty carbon'd up.
Also trying to decide on intakes... I'm thinking I want to stick with one of the OEM 'plastic' ones since they work really well (and the plastic insulates against heat soak) and I'm keeping it EFI. Would it be worth it to repair the dual-runner actuator on this 5.7 Eagle truck manifold I have? Otherwise I'd like to use a 6.4 SRT intake but those seem hard to find. I've also read that the 5.7 Eagle car intakes are basically a plastic version of the 6.1 intake (??) so that might be an option as well?
Lastly what about checking the bearings? I recently found out the main cap bolts are TTY so should I just leave them alone? Are the rod bolts the same or can I pop a few of those off to check and then re-torque them?
