Nice graph.... is the extra power worth the two thousand odd dollar cylinder head job, though? Also, is the OP running a base vortech or 13psi? What are you comparing in those two plots, specifically?

who said I paid for it, it was a nice wedding present from Mr Ten.

Free is always good, and congratulations (belated).
I just meant that from the op's perspective, it would be 25-50 hp (if done properly) for over two thousand dollars, not including labor if he isn't doing it himself.
When I said:
"The statement "I'm making X more horsepower than I should be" is statistically worthless. I'm not saying it isn't true, but a solid pair of dyno graphs (before, after) would go a long way in quelling my skepticism."
...I meant that to really address the op's questions scientifically and weed out speculation, we'd need a dyno of a vortech setup with a stock head, and then one with a modified head - and no other changes.

I will be running about 12lbs on a Vortech SC with the build head and lower the compression with a Head gasket.
Alos like Sideway have mention even with standard boost he still gain quit abit with the builded head.

i see you know a lot about cars
911gt2, if you have the two grand in disposable income and you're pleased with the cost/benefit analysis, then go for it. I'm sure it'll make you power, you just need to decide if the margins make the endeavor worth your money. On that note, I recommend leaving all the extra money you seem to have with me. I'm like a bank, but better...
