all i can say i was not happy with the airgap ran much better with the victor , would pull right up to 6500 where the rev limiter kicked in / ir gap just does not flow enough for a big stroker

mine was maxi ported , just the runner design is not good enough to support the flow needed just can't be done had a few shops look at the airgap and all agreed
Not sure I saw any mention of how they checked out for sealing, seats etc. Care to elaborate? Thanks
No Issues, they were good right out of the box on both the guides and seats. A little gasket matching and they were installed on the engine.
Should go wel with that intake , you should feel a big difference between the super victor and the airgap . let us know how the fuel injection works , i might look into that if it goes well for you
I’ve got those heads, same rockers and am slowly getting things ready for the eventual install. How did your rockers do geometry wise when just bolted on, what correction was needed? Just trial fitting mine on the bench the roller contact is towards the intake a little too much so the shafts will need to be raised some for starters. And did you have to use 5/16” pushrods due to clearance issues? anything bigger a no go or? Just curious, Thanks
I had my geometry corrected @B3RE, as I recall it was a small offset installed..Best bet is to right to the source for that..
Absolutely, I’m just wondering how things for Keith? worked out prior to any correcting and if after correction he had to use 5/16” pushrods for clearance. Purely just curiosity as we have the same new heads and rocker assemblies

I used 5/16 smith bros. This is what I sent michael @ B3.
Engine type, SB 414
Cylinder head type, Trickflow 190
The measured distance between the top of the rocker shaft and the valve tip of one intake and one exhaust. (FIG. A) This seems to vary 4 different valves, .277 I, .266 E, .281 E, .245 I ???
The measured distance from the rocker shaft and the valve stem. (FIG. B) 1.920 to 1.921
The measured distance between the rocker arm bore and the roller tip. (FIG. C) 1.320 - 0.050 (see attached)
The rocker shaft diameter, .6850
The diameter of the roller on the rocker tip, .5460
Intake and exhaust lobe lift from cam card and valve lash, .557 I&E
Rocker arm brand, offset and ratio, Erson standard and 1.6

Here's some before correction pics. I.dont have any afters.
Thanks for the details, those look like Angelucci hold downs which I just received. Did your shafts need to just go up or up and away from the valves? I’ve been looking at how things fit and line up. There isn’t much “slop” in the hold downs bolt hole and bolt to allow for lateral movement but hopefully its just enough to allow some.Thanks!

Ok, all makes sense. I’m mainly wondering about the fitment of the Allen bolts within the hold downs counter bore and hole as-is. Looking at how any relocation will work and what I might be doing to allow any additional lateral movement such as elongating holes in things. From what I’m reading, providing B3 the required measurements can be done with the heads on the bench? No need to have a fully mocked up engine to verify the geometry. If so I can get on this pronto!
That is correct, he can work with your measurements, you should also send your shafts to him as well, he will make sure they are properly elongated to ensure everything works properly
Here are some before and after pics of the Edelbrock Super Victor EFI manifold.
Since this is a "dry" manifold, we decided to go with gasket / port matching at this point.
I was surprised at the amount of material that needed to be removed.

That looks great! I'm on a similar build, but in slow motion. I have a few disabilities, but I'm making progress.
Mine has been a slow roll too.. My builder has been AWESOME, we should be finished real soon.
looks like we will all be rolling out the new builds at the same time . i hope for next week , but **** always comes up
