Hello all,

I'm swapping my cylinder heads out with some Ebay refurbished ones. My engine overheated last summer and I hear seats start droppin' like flies once that happens. Anyway my question is this: Should I also replace the water pump, oil pump and the timing set along with it? aaaaaand I know this is a stretch but should I hone the cylinder walls and do a ring job??

When was the last time all of those components were changed?

Then yes to everything! Timing set should be around 70k. More for the plastic guide than the chain. Cam and lifters wouldn't hurt either while its all apart.

Ugggh I didnt want to drop more $$$ on the cam and lifters but I guess I should consider it. Thanks for your input!

Sorry I didnt get back to this sooner.

I agree...all those items should be replaced with that many miles on the car.

Hmmm...you say 'Timing set should be (replaced) around 70k'. My '06 5.7 has 73k, always Mobil 1. Engine/entire car is tight but I am a fiend for preventative maintenance.
Just wondering, thanks!

Yeah its a pretty involved job unfortunately. I am at 135k and on my second timing set. Both of mine were done at the same time as when I swapped out the cam and other top end mods so it made sense.

The real area of concern is the plastic used in the tensioner guides more so than the chain itself. There is a well known Hemi builder who even recommends 50k intervals for cammed of boosted Hemis.
