MONSTER 7mgte?

[Supra Saiyan]

I am looking at buying this 7mgte for 1200.. Is this a good deal you guys think. The thing was well taken care of. The guy got a new car and his wife wants him to get rid of 2 of his supra and leave him with one car left.. Anyhow, he has better ones than this. This is what he is getting rid of.. See below..

have a built 7mgte forged short block has 10,000 mi ran out of money for project je pistons eagle rods all arp studs r154 tranny perfect working order fidanza lightened flywheel 6 puck unsprung clutch gready lc tunner have ported and polished head with the biggest jdm TRD cams made arp head studs greddy t4 manifold 40mm real hks wastgate big t4 turbo t66 or bigger dont know what mm guessing size not ebay shit

QUESTION A
- Is this a good buy for the price? Its all put together, needs a head and the oil pan put on. Thats it.
QUESTION B
- Can my 7mge head fit with no issues?
QUESTION C
- Should I spend some money and just buy a new head? Is there a head you think I should put on instead? KEEP IN MIND I WOULD LIKE TO USE MY OWN AND NOT SPEND EXTRA MONEY IF POSSIBLE..

FACT (Or so i was told)
- He said it was making about 500hp, and was UNTUNED..

Let me know what you guys are thinking..
