what to upgrade, replace during head swap and with what???
I'm pulling my engine ('96 4.6L Romeo) out to swap heads (renegade NPI's) and headers (kooks) in a couple of weeks.
The car has 113,000mi, but due to our plastic intake manifold, Ford rebuilt or replaced the block at 30k, so the engine has about 83,000mi. Due to a second manifold crack, I now have the upgrade manifold.
Eventually I plan to either rebuild the bottom end or buy a built short block (renegade) and may go with either max compression N/A or, more likely, low compression and max SC boost, but that's down the road. For now I'm gonna run N/A with massaged NPI's and PI cams...
For this head/header swap, I intend to use ARP head studs, a one-piece crank sprocket and steel pulse wheel.
My question is:
While the engine is down and apart, are there other parts I should upgrade/replace now, or should I wait until I do the bottom end???
I assume the above will bolt on to the new short block??? Should I do all, or some of the above?? is there more I should consider??? why??? and do I replace with OEM or is there something better out there???
Please don't tell me to scrap the NPI heads and go with PI's.. that decision (for better or worse) is already made and the heads are on the way. NPI's fit into the "grand plan."
I just want to know what else I should consider doing while the engine is on the stand... It may be some time before I do the bottom end... unless, of course it gives out sooner....
All input will be appreciated, some may be acted upon, some shelved for now, some may even be ignored, but if you have experiences/opinions I'd like to hear them...
