L92 vs. 317
Alright guys, I have both of these heads for my 6.0. The l92's are on it right now with a victor jr and a carb. I will be going turbo and fuel injection soon. Which of these heads work best for boost. I know the stock flow specs of each head so I am educated in their naturally aspirated potential. I would need to buy an intake either way I go.

My L92's are bolted on with arp's and mls gaskets so it setup good right now. I do have a truck intake along with the 317's I already have in the corner of the garage.
I would be fueling it with megasquirt. I guess I am just trying to go fuel injection as cheap as possible for right now. Just until I can get comfortable with tuning it. I could just buy head gaskets and slam the 317's and truck intake on it just for now to get my feet wet before i go turbo.

I have off the shelf l92's (no port work) with upgraded springs, yella terra rockers and caddy lifters on a 402.. made 633rwhp on just 8psi with twins...original APS kit and turbos. im switching my set up over to a F1A and will be using the same heads at 15 or so psi...should still net good results...they flow very well as stated.

i have patriot performance 317 stock ported heads on my car and been almost 154mph. had the car up to 24psi from the 19psi i have ran and seat of the pants says they are making even more power lol

Honestly I'm ready for fuel injection. I'm a little tired of the carb. It runs different every time I get in it. The wideband tells me so lol. Don't be offended but I think fuel injection is superior to a carb when it comes to drive ability and forced induction. I love the power that my carb makes but the drivability can suck sometimes. Mostly in the transitioning from the idle circuits to the primaries.
The fuel injection intrigues me and seems to be more consistant. With a good tune that is.
