Or should I buy a new head, machine my block down to level and go from there?

I've got a buddy who swears by this stuff.
800+whp LS motors, 700+ whp 4G63s, etc. He really globs it on there - may be worth a try,

It is eating coolant and the oil is milky tan...

Well in that case... I just remember the disappointment at the clouds of smoke on startup of the first engine I built and somebody told me later "oh yea they always do that".

The m52 that I picked up for $380 is shot. Cracked head and the cylinders need to be bored out due to rust from a head gasket leak. I could use the block and bore it out to 87mm for my pistons.
Anyone have a m52 or s52 from an automatic car? Preferably owned by a grandma who had a 50 mile daily freeway commute in a 55mph speed zone.

I on some fronts, yes. It was a junk yard motor he didn't have any knowledge of.

Not much going on lately. Trying to figure out if I should mill down my S52 block to make it perfectly straight, o-ring it and run a thicker MLS gasket. Do the putty thing in the combustion chamber to make sure I'm okay.
Or..
Build up one of these m52s that I have been slowly collecting.
Positives for decking the S52:
- Use the parts that I have
- cheapest route
- more torque
- I can learn megasquirt on a used motor
Negatives:
- there was some detonation so my rods and pistons might be shot (I really don't think they are)
- thicker head gasket makes for a weaker seal.
Build M52 positives:
- take what I've learned from the s52 build and make this one super solid
- Better head gasket seal
- can run more boost in future
Negatives :
- $$$$$$$ (house projects and getting the M3 back on the road are priority.)
- Would also like to buy a Blunttech T4 tubular manifold and a big turbo for a lot of boost. $$ (I would sell my turbo, t3 manifold, down pipe and exhaust to compensate)
- 4 in downpipe and exhaust to be made $$$
- Did I mention $$$
Please let me know your thoughts on this. Any input would be greatly appreciated.

Swap in an L*.........
Just kidding
I vote option one with the s52 since it is the cheapest route and you can enjoy the car while doing option 2 if you so please=)
I'm leaning this way. Thank you for the input!!
If I do a LS it would be in a Datsun 240/280z. I have my eye on a mint 280z at a buddies just getting dusty in his barn.
