Excited about these LS3 10* F310s that Frankenstein Just released! O-ring exhaust flange, centered exhaust ports to valves, raised runner design, O ring valve covers, pedestals to run LS7 rockers on them. Minimum bore of 4" 2.180 1.615 stainless valves. Saw some 3rd party dyno test and crazy how they did against the competitions LS7s vs these LS3!

They threw a lot of tech into those heads!
How 'bout a shot of the chambers?

Can you share any of this data? I was pretty happy with the set of ported TFS LS3 heads which they did for me a few years ago. Those were a smaller port than these but did a nice job in my setup. Curious to see what these can do!

On my way there, I'll ask if I can share details yet. If so I'll share what I can.

Can't say that I have. Nice touch though, huh?

Big Block Chevy, yes. Not on an LS though. I caught a few of their pics on FB. They look great.

I sure as hell won't ask how much they cost

I spoke with Chris Frank a few days ago about some heads for a 416. Chris said they expect to have a before/after head comparison from a dyno this next week for a blown vehicle; based upon the amount of fuel they needed to add, he thought it would pickup 40-50HP.

Great looking heads and they are a work of it but the money spent is not really worth it.
You can CNC a set of LS3 heads and they will make identical power and cost you a 1/3.
Will also hold up for the majority of applications.
