408 or gen 3 hemi

The valve seat isue seems to be limited to the early 5.7stuff,-09 and newer dont seem to have that isue, stock eagle/SRT/6.4 heads willl kick pretty much ANY Stock style LA/Mag heads *** so hard its not even funny,yeah i know some people might be able to get close porting some stock style smallblock castings but still that's just to get close to what the stock gen3 already does from the factory.
The gen3 heads are serious stuff with their straight raised ports there is just no way around that part.

As for the rods, who still uses stock rods in a new LA build that is anywhere near serious? rebuilding stock rods will cost more than getting a set of new rods that are also lighter.

Not arguing for the sake of arguing, some like their small blocks and some like a HEMI. We all have our preferences and we should build whatever fits our desire that's why we do this stuff!
I was going to post a response to this but if I do, it would be a small book. My point is I have done this for nearly 50 years and I've seen and done stuff that so many will never see or do. I'm not just some guy that comes around here for entertainment. I've done professional port work, engine work, transmission work, differentials, transfer cases, passenger car to heavy road and industrial, for more people than I can name, worked around and with people that are or were the ones that set the bar or everyone else, that have made it around the world in competition, sponsored competition stuff from pullers to rounders, drag, commercial transportation, industrial machinery, ag. It sounds like I am bragging to most but the truth is if they actually knew the truth, well it wouldn't be bragging, just stating history. My name only means something to those that knew or know me. I was always in the background not in the camera or at the parties after it was over. Fact is there are so many people like me no one ever knows, only those that pay the bills.
