Weld aluminum head together?

admin

Can an aluminum V8 head that has been cut in half be strategically welded back together? Was cut between the cylinders down the middle of two head stud holes. Only water jacket and oil ports are cut threw, cylinder chambers, valves, intake and exhaust ports all intact. Looks like basically a 1/2" thick casting all around to be welded back together and a little extra work around the oil ports. Being cut right on the headstud holes I believe would be a plus if this can be done.Anyone done this? Any tips? Is it funny?
Reply:Seems to me welding it wouldn't seal the jackets from potentially leaking into eachother on the inside. But I'm probably picturing how it's cut incorrectly in my head.plus, as said in another thread, you gotta bake the head to get all the oil/water out of it and make sure it's perfectly clean.Hobart EZ-Tig newbie.
Reply:Sure But I would not intend on using it on a working engine.Last edited by Fat Bastard; 04-10-2012 at 04:55 PM.

Reply:Why was it cut in half?This is the important part of the story...
Reply:Way back when there was a 300-6 Ford powered Maverick called "I coulda had a V8" that ran out of "Andy's East Coast Speed" in Rhode Island and he ran the car at Connecticut Intl' Raceway and the head that was on it was made from the centersections from (3) 351 Cleveland aluminum heads welded together and this car ran in the hi 9 second range back in the early '80S with a 4 speed..So yes it can be done and work but I have never done it and don't ask me how they did it....zap!Last edited by zapster; 04-10-2012 at 06:16 PM.I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:As Zap said... its been done before. Would have to cut windows to get to certain areas, then put windows back in. With all the aftermarket stuff available there would have to be a good reason to do this (expensive). What head are you needing/why?PeterEquipment:2  old paws2  eyes (that don't look so good)1  bad back
Reply:I am actually unsure what the heads are yet. I am guessing from something that wasn't a V8. Probably something that has been around a track or something.
