99RCSB Broke because I wasted thousands and thousands of dollars on my truck.
I guess the first question is, what turbo are you going to be running and on what engine? Stock 5.3 block, forged motor etc. But im curious as well
1951 3100
1984 C10
Yet to be determined. I guess a forged 370. or 408. idkOriginally Posted by duckysbht

i like L92's for there price and they amount they flow
2006 silverado SS....Clifford Jr...turbo coming soon
1970 Chevelle ly6 swap....d1 coming soon
see problem with L92s is there thin decking. a stock head is about .5 thickness the L92s are about .45 thick. now what makes the AFRs a great head for boost is they have a .75 thick decking. these allows for better sealing of heads when comes to higher boost levels. they say up to 15lbs heads seal fine without any question. now anything above that its questionable if they will lift or not.
now even rick from syenrgy even spoke on how he doesnt like the L92s for boost and the 317s are much better for performance.
Parish made his 1011rwhp 1070rwtq with stock 317s on his 408.

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
317 heads off a 6.0L on a 408ci motor will hold about 20psi of boost and will make around 1000-1100 rwhp. This is the budget way to go.

I'd love to know the cam specs on that motor and how big the down pipe was.

Yeah I was just curious, it would have sucked to run LTs or something then turn around and throw some heads on there and not having them fit or being too small or some coincidental BS
