My car is at the mechanic place the head needs rewelding i think and the cam shaft is broken so i have to another one of them but fixing the head and cam will that give me more power
Well if your current head needs welding up (WTF?) and the camshaft is broken (WTF?) I am pretty confident in predicting that fixing those will give you more power.
How the hell did you break a cam??? The timing chain would snap or shear the teeth off the sprocket before the cam broke. If this did happen or the cam did break it'd throw the valve timing out to buggery and send the pistons smashing into the valve, ultimately meaning the motor is well and truly F**KED! If you did do it, how?? It's a pretty classy way to blow an engine IMHO.

If you got a EA-D put a EF/L head and cam in it. Bit more power and pull. Pretty shore the EF stuff fits straight on a EA. guessing EL stuff should fit..

Don't get your head welded!!! It just don't work on alloy heads very well. Your mechanic is a dickhead for suggesting this quick fix.
Go and get another second hand head from the wreckers and take it to a engine rebuilding centre and get them to check it out for you and recondition it. Then it's just a matter of getting your mechanic to put the new head on for you and she should run good.
the head and cam was already like that my mechanic said i don't know how u can break that shit i had a mate look at it and he said the owner before me must have drove it hard to do the shit
The new heads are cheap, but ot's the rest of the crap that goes with the head, valves, springs... that cost a fortune. Price up a head for the series 2 EL (yes there is one as I have been screwed before when changing a head on a series 2 EL). There like $650 - $800 Dealer price!
Can we get some pics of the cracked cam?

A cam can quite easily be broken if it was manufactured incorrectly. Bad casting gives them weak spots. (an air pocket inside the metal).
This type of incident is more common in the old push rod engines probably because there is more load on the cam. I know of a few people who have demolished $10,000 engines as a result of this.
If I were you, I’d grab another head, reco the thing, and clean up the ports while your at it.
As for a cam, grab a s/h one (For $50), or better still, something like a crow #2.
