stock heads ls1 hp limits
440-470 is at least 100HP over stock. were not claiming 100hp gains from P&P heads alone.
40HP out of the heads and 60 out of the cam and bolt on's = about 100HP over stock.
Yes I know, that's why I bolded it. I wasn't implying that AI was trying to claim 100hp over stock from their P&P alone. wtf is wrong with you guys?
I know AI does a good port and polish job.

if you re-read what you bolded then what you typed, it sounds like your were trying to imply the P&P job AND cam and bolt on's was worth 40-55 HP.
