I have tuned many L92 combos, not all that impressive. The stk heads ported with a Ported FAST and a decent cam will make the same if not more power and significant amount more TQ. The L92 heads flow great but even a Ported LS3/L76 flows poorly. The FAST is superior now when they come out with a LS3 based FAST this may be the ticket. I am not that much of a fan of the monster intake runner CCs of the L92/Ls3. The cathedral port is much better for lower and mid range TQ.
I have seen people go down the wrong road over and over again.
If it were me doing a bang for the buck build:
Stay stk bottom end make a nice H&C combo 450RWHP to 500RWHP depending on how far you want to go.
You are not even making 375RWHP now, 75hp inc is very substancial.
If you gain enough TQ you will hate the 410s. It will render your back tires useless.
I have a 6L w/ ETP heads, ported FAST 236/240(you'll want to be a bit milder 232/236 or so) DT Long tubes, and it makes over 480RWHP and 420TQ just getting broke in 130miles on her.
With some thinner oil and break in about 10k miles Id expect 500RWHP.
Thats my humble opinion
Thank you and God Bless
