Someone I know over here has just bought a 03 2500 5.7 Hemi, seller sold as faulty with suspected HG, turns out it's dropped a valve seat on number 1, I guess over in USA this is no biggy, here in UK it's pants down and assume the position, Rockauto has reman heads for a reasonable amount, I've advised to replace both, cylinder looks from pictures to be scored I did say rock for pistons/rings etc but then noticed they sell a cylinder repair sleeve, anyone used this ? Has the Hemi got liners or is the block bored big and the sleeve pressed in ? if thats so he would at least need info from a good shop over there for the bore size as no one here would have a clue how to do it.

Any help or advice or parts appreciated

@Dynamic just built up a hemi engine for his little truck you might talk to him.

I came across this.

As for low cost cylinder heads all ready built, there are a few machine shops that did videos about how bad the heads were. You get what you pay for.
