Looking for a set of unmolested good condition 862 or 706 heads. Main reason for the need is fixing the exhaust leak from broken bolt during long tube install. Yes I already tried an extractor...got the other 2 bolts out...but it destroyed one bolt and ruined the hole. Only options I have are replace the heads, I'll probably have them milled and cleaned up, or drill a larger hole, re tap it and go through that bs which I don't want to deal with so swapping heads is ultimately easier :lol:.
ill have a set of essentially BRAND NEW 706s here in a few days. theyve been all cleaned up, milled flat and valve job... ill let you know when theyre done
Thought of doing a helicoil to repair the thread? There is also another thing you can use to repair it called a case-saver, you tap it to a much larger size and thread in a steel insert. Works great on really messed up areas. Volkswagen used it forever on the air cooled engines.
The thought has crossed my mind yes, but I don't trust myself to not mess up with a drill and punch through to a coolant passage or something like that. Is it likely that it will happen, no, but do I doubt myself when it comes to stuff like this...yes.Quote:

Bump
you too good for my heads?!? :(
Mitch gives good heads.
Mitch-I told you yesterday IM BROKE!

I just helping him out. Bring your old head and ill fix it for you.
Damn that's a hell of a deal! Looks like I might be making a trip out to the west side soon haha.
I have a set of 862 heads if your still looking
why not have a shop weld the hole up and retap it, i know if craig can repair the damage to my ls3 head i know this could be easily repaired.. ill post pics once my head has been repaired, a good aluminum welder that knows how to weld aluminm could fiix that for less than 50 bux easy
I am just waiting to hear back from the guy above actually. Been trying to meet up and pick up a set I just havent had time, and when I do have time hes got something going. :lol:Quote:

well as you know ( i think ) i went with LSA heads for the thicker deck, well livernois did the cnc which they used a ls3/l92 program, something happened and made the intake runners to thin, then after porting they became thinner :( well after install i had a smoking issue on driverside ( dual exhaust ;)) come to find out i had cracks up the runner to the valve guide , sooo livernois is cncing a new casting, then James at rage will port them like my last heads, which the one that got damaged is being repaired for a nother setup i have.. which is a l2 engineQuote:
