Hey guys, I really didnt mean to start anything with this. I am sure that you both have good quality heads, and I personally, have a hard time believing that either of you lack the knowledge to claim what you do. You are both reputable companies and seem to have a good rep. with your clients. Thanks to everyone that offered their advice.

You can cut up to a 2.04" valve job in a stock seat. Therefore any valve up to that size can be put into the stock seat. With our cnc valve job machine we can instantly adjust the valvejob size for bigger valves or for different valve depths. If you design a port for the valve set to a certain depth then you can easily keep the valve at that depth. Installing a 2.04" intake valve with a 2" installed height would definately hurt p/v pretty bad, but sinking them .015" or so helps to offset a lot of the bigger valve. We've spent hundreds of hours testing different valve sizes, depths, and angles. Rest assured that if I say we can sink the valve a little bit without compromising flow, then it won't.
The torquer 2 has been installed many times with several competitors cylinder heads that have 2.02 & 2.055 valves. We've built Stg 2.5 heads countless times to work with the T2. If anyone has any questions or concerns call the shop & talk with Jason, he's built enough different valve/depth configurations to make you go CRAZY!!
What a lot of guys don't understand is we can instantly change ANY length or angle on our valve job. VERY VERY few shops in the entire country have this ability. When you can have complete adjustability in your valve job, you can make changes to adapt to different depths & different flow characteristics.

Have you ever measured PTV on a T2 on a 112 LSA, (+0 or +2 or +4)?
I had the T2 with PRC stage 2.5 (MINE is a 113+0) on a stock block.
I had .085 intake and .11 exhaust, the 112 must be tighter than that, but by how much?
