Ask yourself what are the plans for the build 1st. A 500whp+ setup isn't for everyone. Like people have mentioned here you will need more cam, more converter better fuel and lots of fine tuning. Those shooting for the number either are guys who drag race them at the track or do highway pulls. I made 537whp running a 5200 stall, 3.91 gears and on MS109 for fuel but was a rack only car that saw little to no street use. 3yrs it was a 10.40 all motor car fun at the track but rarely saw the streets. If this is your daily driver I'd just port the heads and rod mod on the stock intake and your golden.

I’m in the same next mod situation, I plan on milling my stock heads and having them cnc ported, I’m running a btr stage 2 cam, kooks long tubes and did 440 rwh , stock torque converter , runs well and very streetable, my question is don’t the L99s have a factory valve relieve ? and how much bump in compression would be practical say with a stage 3 cam ?

Use the Pat Kelly compression calculator. You have to know the advertised intake and exhaust durations @ .004" and know what fuel you plan to run. A dynamic (not static) or effective compression of 8.75:1 is about the max for 93 octane. Best way to know is to degree your cam and have your head's volumed with the valves your going to use after all the machining has been done. From there you can measure PTV to see how much more you need to cut from the heads to get the compression your after.

Just for reference, I did this with my G8, got my DCR to 8.69:1 with a . 035" quench, a 220/224 111 LSA Cam motion Cam, netted me 470Hp / 450lb torque at the wheels. This was from a 6.0L through an A6 trans, stock stall, stock gear. I suspect with a rod mod intake, the car would have hit 500hp or really close to it. The 6.2 being a tad larger should have no problem hitting the 500hpark or higher if it's done right, without a huge cam or ported heads.

If you can get compression up into the 11.5:1 to 12:1, you can really take advantage of the compression with added timing and E85

Nope, it was a custom ground Cam Motion cam. The Rick Crawford cam has a different duration and is based off a lunati grind. Though the Rick Crawford setup is solid for sure. It's not what I had.
