Another option is the Harland Sharp roller rocker valve lifters. Most bump the lift to 1.7 to help motor breathe better. If you plan on doing cam and bottom end, get the 1.6 ratio.

I was going to pull my motor and rebuild like the OP. But I found that I can buy a new short block crate motor cheaper than I can rebuild the motor I have and I can go to a 360.

Reusing injectors, lifters, rods, rockers, most sensors and all that good stuff
After my rebuild experience with leaking head gaskets, I recommend decking both the block and the heads.

On a second thought going from a 318 to a 360 might not work unless the computer is replaced. But don't know for sure it would have to be replaced.

You would run lean in open loop. Not a good idea..... You could pick up a Mopar Performance PCM, or go to the parts store, and simply order the correct one for the 360. Wouldn't be able to do too much in the way of internal mods though, as it would confuse the PCM, and reprogramming the older ones is expensive......

i actually just ordered these heads. their customer service is GREAT! i talked to a guy named tim. i phone ordered my heads through them, because theyre being custom made for my new engine.

i would suggest replacing lifters, and push rods. going with some harland sharp non adjustable roller rockers wouldnt be a bad idea either. you can get either 1.6, or 1.7 rockers. stamped rockers(factory) are notorious for not being true. you will never find 2 of the same rockers. which is why you get such a great boost in power when you go with roller rockers.

You sure like spending someone else's money. Why replace the lifters and pushrods? The lifters should be inspected, dismantled, cleaned, and reassembled. If the pushrods are straight, just re-use them.

i wasnt spending his money, i was suggesting... the truck has higher miles. the lifters are cheap enough, so just replace em. mopar performance lifters can be had for about 110 from chrysler parts direct. push rods are a bit cheaper than that. just good insurance...

150K on more modern engines should no be confused with just under 100K on engines from the days when valve lash needed to be adjusted.

I would suggest the OP have a competent machinist inspect the lifters first before tossing them and going new.

With all of the "money" everyone here is spending, he'll have $6-grand tied up in that thing
