Default Spun bearing on my EJ207

And it had all gone so well..... I scored a prebuilt 207 from another member with forged internals, v7 crank, built heads, etc and I ran it on a street tune for ~1500 miles. It has all the proper break in procedures followed, but apparently the clearances were off for cylinder 3's bearing (too lose) which spun this weekend . Luckily, it failed in such a way that I'll only have to have the crank repaired, but since I have to tear down the block, does anyone have any recommended upgrades?

I will have to replace the gaskets, studs, and all bearings. I've also read that I should replace the oil pan, pump, etc. I already have forged pistons, rods, double springs, sti valves, and 280 cams. Should I get a TGV delete done while the engine is apart? Port and polish? Any recommendations? I DO NOT plan to take this engine apart again if I don't have to. LMK, thanks!
