Flow numbers dont lie, if you are too blind to see them for yourself drifthappy, well i'm glad i'm the one building my car and not you.

Since you wanted to bring up the guys post, first he stated that they flowed x amount, then I provided proof to the contrary, and he had to admit he was wrong, and in the end, yes the 1UZ heads IIRC (dont quote me on it) did flow a little more than early 5.7 LS1 castings, however get stomped by the stock truck heads, on my truck engine, and I didnt even have to get into the L92 heads which are like a 10 lb sledge compared to my ball pein 317 casting LQ9 heads.


But hey all of this i'm sure is over your head, as you have a hard time with the concept of making a cast manifold, so I really dont expect you to be able to understand how head flow numbers result in power, especially in an NA application.
