![Question](/forums/images/icons/icon5.gif)
Im going to be going through the heads on a 500efi.
To my knowledge is based off of the ram jet 502 motor correct? What generation would a motor built in 03'?
Also, is the entire valve train Crane? I need to replace a lifter.
Do I need to retune this motor after doing the work, I am going to keep it stock for the most part.
I had a push-rod break apart, so I am going to rebuild the top end. I was right around 325 hours. Lucky for me all the pieces stayed in the valve area.
I'll keep posting the progress.

i would replace all the springs,lifters and get a good valve job. i would also take a good look at all the rocker arms&pushrods.03 is a gen6.i think most of the valvetrain is crane but not the lifters.

i personally would not use pro comp rockers,the crane golds are pretty hard to beat.i also like the scorpian endurance rockers and they are american built by american workers.your engine already has inconal exhaust valves and stainless intake valves so if they check out ok they can be reused.the valve springs mercury uses are not the best and i recomend something like the isky springs.

Also I still need help identifying the lifter that came in the motor.
Thanks for the support!

Massive shortage of crane golds lately. Seems nobody has them anywhere.
I would stay away from the procomps. Just about everything from pro comp is questionable. The comp ultra pro magnum XD looks like a nice rocker arm , and its steel. The older comp cams steel rockers, i dont like. Im going thru my tops ends currently, and going with crower enduro stainless rockers.

Ok, I might have spent too much time in the motox world. pro comp are junk, but comp cams are not? Are they the same company or am i missing something.
