Yea man, you'll be good to go with the stockers, but from what I've read it's silly not to put new lifter trays in there since they can wear and the new ones are only like $7 a piece...

 

Might as well get new ones then if they are that cheap. Thanks for the help

 

That is one this that is super cheap for our motors!! lol

Also, some people drill small holes at the bottom of the trays for the oil to leakdown faster. Second, the seats of the ls7 lifters are slightly taller and some people have to change pushrod lengths.

Hope that helps!

 

Yeah with the heads being milled and having different lifters I'm borrowing a pushrod length checker to make sure I get the right size. That's a good idea about the small hole in the lifter trays... might have to do that.

What should I use to clean the carbon build up on the pistons? I was told to apply a little bit of oil on the the piston and cylinder walls and rotate the engine every couple of days to keep it from rusting. Don't need anything screwing up lol

 

i used a wire brush on a drill to clean my pistons. yours are pretty clean tough. sea foam and a scotch brite pad.

 

looks great luke good luck on your new set up

 

Heads were shipped last Thursday

Was also told by Dave at WCCH that the drivers side head is a little reddish because its a sign of the engine running to hot. He said that it only takes one time to do it, but i did have overheating issues a while back so it explains it. He also said that there is a TSB out on some 706 heads being faulty and causing some 5.3's to overheat easily. You learn something new everyday.

Can't wait to get the 243's back richard

 

I noticed something cool. You can actually do a head swap on these trucks without removing the accessory bracket? I'm going to be doing the same thing as you in a couple of months. Tell me, how long did it take you to tear it down to the shortblock?

 

not near as long as it takes to put it back together lol

about an 1 hr

 

How can I find out more about the 706 heads being faulty, I have a set of those and at idle it wants to get hot, I'm putting a new radiator and bigger fans to cure it. But if it's the heads then It won't get fixed that way.
