Don't know how I missed this. You prove some valid points but they still go in my favor. They also put those big heads on a 4" bore engine... Not only the LS3/L92 got the square heads. The TFS and LS3 heads I'm comparing are two totally different port shapes and runner designs however the TFS head will still shine over that LS3 head on a 4" bore engine with it's smaller valves. I have all the data for TFS heads... Tooley is 30mins up the road from me.
On this setup the heads will be fine especially with the big shot of gas he's gonna be running through it. I'm not so sure on the camshaft selection personally but maybe there is something to that cam that I don't know. It's worth a shot!

When you throw a cathedral on there you are better with the smaller valves but give those 245's the same valves as the LS3 and watch them choke on a 4 inch bore just like the LS3's

Yep I agree a 2.160" valve belongs on 4.060" bore or larger however that is not the case for this combo with the 245 heads. The valves are no more shrouded than the 2.160" is on a LS3. I'm interested to see the results from this combo. I offered some dyno time to get the setup dialed in just for testing purposes and to see what it'd do at the track.

Lil John did one not long ago that had a ridiculous size cam and on the bottle it woke up like a ****... I know it's not the norm but I'm still curious to see how it does.
