the blower grind uses the stage 1 intake cam and the stage 2 exhaust cam profiles The turbo grind, like you said, is a completely different grind though

now that information i did not know. it actually helps if you can get those cams specifically, but you would need cam gears to dial em in right?

there really arent any benefits. the LSJ head BARELY flows more than the L61 head, and the valvetrain is the exact same excluding the valves.
