Get someone to weld up the lobes and get your HKS grinds put on the lobes.
Any half decent cam place can do this. Will set you back 5-600 though.
Definitely won't be able to get new billet 5MG cams today. Like Glenn said, maybe in 1985.

glen,
dont need 'blanks' ...
get your cam lobes welded up with new material, and then regound back to the spec yopu want. damn twincam engines (though youve only got 12v) youre prolly looking around the 1000 mark 
and in reply to your PM the other day...
eds list of easy performance DO's
shave head as much as you can without hitting vlave/piston fouling limits, and then get adj cam gears. get your comp/r up as much as you can (assuming you cant get pistons).
do a decent port job on the head. also polish the piston domes and comb chambers to make use of the higher comp with BIG advance 
get the bottom end balanced and blueprinted
get a lightened flywheel (cromo)
theyre prolly the simplest things you can do that will yield decent results.
wtf happened with your mum dude!!
cheers

Oh and get a machinist to mill 1-2 kg off your crank dude.
Send me an email and I'll send you a short list of cam people in Australia.

you also will find toyota race cams are made for all the twin cams they use the same profiles from 2tg to 7mgte from 256 duration to 320 duration it just depends on the cam lift and how hot you wont to go i am running 304 duration and 535 thou lift cams in my 3sge motor ,and daves 2jze has 304 and 290 duration cams in his motor

Actually, they're both 304 duration 435 lift Glenn.

Yeah he did but he got them the wrong way around, so just got the small one made lumpy. Now they're both the same.

All sounds pretty complicated man, before you go spending shitloads of money remember that the 7mgte is an easy and reasonably cheap conversion into the MA61.
just an idea

OK dude. Email me.....I will supply you with a short list of cam grinders in Australia. You then tell them the cam specs you want, and they can tell you what they have. They may not have exactly that grind, but they will have something similar.
Tighe Cams have over 5000 different grinds.....surely they'll have something close.
Important numbers for that grind are 284 degrees duration, 230 thou lift (at the cam, rocker ratio 1.5), and 220 degrees duration at 50 thou lift. This is what the cam guys will ask you.
Just wondering where you got those specs? If you got them from a cam shop, they will probably have the profile too.

Gianttomato - how heavy is a crank if u can take off 1kg?
|
I struggle to lift a 7M-GTE double-counterweighted crank off the ground. The 6M crank is not quite as heavy (single counterweights) but still weighs heaps. You wouldn't have to try hard to shave 1kg off something like that.

Those 4 and 5M cranks weigh well over 20 kg (possibly even 30ish). I can't even fathom what a double counterweighted 7M crank must weigh.
It'd actually be pretty easy to whip off 2kg no probs.

you friggin BIG GIRL'S BLOUSES!!
hehehe, seriously, yes the double counterweight crank is heavier than the single, but not by much. not much at all. never weighed them on scales, but to the hand, there's not THAT much in em.
i mean, its all of 2 counterweights different (pistons 2 and 5), and if you look at where the counterweights 'would' go on the single counterweight model, its pretty beefy anyway. so not that huge an addition.
that said, whilst norbie, you are a big girl for not being able to pick em up off the floor, they are very heavy
GT - whats the milling worth? in ballpark terms??
Glen - the weight lost off the counterweight wont so much give you abs power, but will improve throttle response. that said, itll have less angular momentum, so the engine wont be as smooth, and will feel a little on/off...
cheers

Surely if the milling was balanced this wouldnt happen?

balanced just means it wont have harmonic vibrations etc.
but, if you mill your counterweights, the crank weighs less at its periphery, which means it has less angular itertia (making it easier to get spinning) but also has less angular momentumn once spinning (more easily slowed down).
so good throttle response, but back off the loud pedal, and the engine will slow down more quickly too.

Like how bad are we talking here when one backs off?
as in noticeable over stock but not annoying?
compared to perhaps revving out 3rd quite high down a slight slope instead of changing to 4th and having a large amount of engine braking slowing you down right away?

I rand wade cams a while ago, they said they'd make cams for my 4ag for about $220 each new from blanks, at that price I really wouldn't want to go messing with welding the buggers!

Michael, have you tried sourcing these for a 5MG? 
Unobtainium nowadays, so welding up lobes is his only choice.
