Aluminum Head

Repairing cracked aluminum heads?

If a aluminum cylinder head is cracked between the "intake" and "exhaust" valves, what is the best method of repairing it? Do you tig weld it or drill and plug the crack? Or, is there something else that I don't know of? Please explain which method is better and why? Thanks.

your better off taking it,,to a shop,,and maybe exchanging it for a good one they are really hard to weld up,,you can tig weld them,but the most of the time it wont hold,,id exchange it,,and get a good one,because this is going to be more of a headache than i think you realize to do,,i own a repair shop,,and have tried it before,,and i had no luck with making one last,,i finally just got a good one,,and put on it,,good luck with it,,i hope this help,s.

Does a M43B18 BMW engine have aluminum heads?

I know pretty much everything else about this engine but this is te one thing I can't find. It'd be nice to know as the aluminum heads can be ground a lot easier by the right people than say steel heads. Any input on this would be great. It's for a 94' BMW 318i. Thanks!

I am not sure, but it is not worth it to work these heads over. Why buy the bottom of the line engine model and then try to increase the power?
