about myself i feel these 21* LT1 TFS heads will be better than ported stock LT1 castings specaily when reworked correctly. about myself i will try these 21* LT1 TFS heads ported by AI in my 1996 LT1 caprice impala SS with AI ported LT1 intake manifold and custom cam from AI.

I believe so. My mistake. Am I looking at the wrong heads here also or are they keeping the same name...?

in hi-resolution.
AKRON, Trick Flow Specialties introduces the best-flowing cast cylinder heads available for naturally aspirated LT1 engines: Trick Flow GenX™ Street/Strip Cylinder Heads. Out-of-the-box, these heads are easily capable of producing well in excess of 500 naturally aspirated horsepower.
Trick Flow GenX Street/Strip Cylinder Heads for GM LT1 feature 54cc combustion chambers to maintain the factory 10.25:1 compression ratio, but have CNC-profiled and bowl-blended combustion chambers to maximize performance. The heads have 21° valve angles—reduced from 23°—to increase piston-to-valve clearance and unshroud the chambers for better flow.
GenX Street/Strip Cylinder Heads for GM LT1 also feature 185cc intake and 67cc exhaust Fast As Cast™ runners that duplicate the port shape and profile of fully CNC-ported runners. The result is near CNC-ported power and performance for the same price as standard cast cylinder heads—and the best-flowing cast LT1 heads available.
The fully assembled heads come with stainless steel 2.020" intake/1.600" exhaust valves, GM LS-style 1.300" double valve springs, chromemoly steel retainers and locks, guideplates, and ARP 3/8" rocker studs. In addition, these heads retain the use of all stock sensors and fittings. Bare cylinder head castings are also available.
Based in Akron, Ohio, Trick Flow Specialties offers products that provide "Ultimate Bolt-On Performance." Trick Flow's product lines include cylinder heads, intake manifolds, camshafts, valvetrain components, and more."

Waiting for the cross section we need for 400 inch engines. All you CNC houses, get teh machines warmed up and ready. No one need170-185 cc heads like these guys are saying, the market is flooded with "average" heads
Sure you can make 500 hp with some fo the stuff and solid rollers with lots of curtain area and open time, but we need real heads on par with SBC and LS1 stuff. A 400 inch hyd roller pump gas LT1 should be able to go 9.something without nuts camshaft or 3000 lbs. Its an engine like all the rest

There is a thread with actual data and photos of these castings that we started here: https://ls1tech.com/forums/lt1-lt4-m...info-pics.html
A 350cid stock shortblock LT1 could probably go 9's with our cut factory heads & a near stock manifold if one were inclined to work hard enough at it. It is sometimes difficult for any manufacturer to determine whether or not they should produce what you guys need, or what you may have been lead to believe you need. In the end the probability is that we will produce both as detailed in the thread about these heads

People buy and build LS1 stuff because you literally can throw together a low 10 second NA car with shelf stuff, and be simple/reliable/driveable. Withotu turning it into a project (and not many want to "project" a LT1 car, they just get into a LS1) your going to need cubes as much as you can get reasonably, and enough cyl head to feed it to 7K without long x huge solid roller cams. If you dont have enough cyl head you can crutch it w/ cam somewhat.
Give me a cyl head correct, we have 408 inches and hyd stuff, no reason why you cant see 10.40s NA at 3700 lbs like normal LS1 stuff. I hate damn pushrod pinch - anyone make a bad *** 5/32 pushrod

With a hyd roller, your more limited on what you can get curtain area wise with the cam, so need a head that can move a good quantity of air, move it well, in the time alotted. 240 some degrees, not 280

It could, but more so as a function of camshaft for days aftermarket computer and 9500 rpm. No one wants to build a super stocker LT1 (sorry Gizmo!
) but a few people.

Why can't we have heads that are badazz out the box like the LSx guys and they get to run them with streetable hydraulic cams. If the stock LS1 and LS2weren't bad enough they get relatively cheap L92 heads that flow 320 CFM out the box with no requirements for exotic and expensive stuff shaft rockers and solid roller cams.
They get to run 10's all day long at the track then get 20 MPG's on the way home and may even pass emissions to boot!

So are these available yet? I have a set of new LE3 heads with 2.05 valves and solid roller springs sitting here, but I would much rather sell those to use these 21* heads ported out. I think my future 385 E85 build would much rather have a set of these ported to 215+ cc's.
Anyone have pricing/part#'s on these heads bare yet?
