2.02 or 2.05 Intake Valve?

[273]

The Edelbrock Victor head build that top well over 700 hp was done with a cam @255 intake duration. The CID was IIRC, 376.

Think it's this one

737-770 hp 376

So a 2.05 won't help much? After spending $2000 that's totally out of the question.

The cost of the valves and the valve job ..even without a blend, it'll pick up power.
So....
Is it worth it?

I should clarify. Someone commented about getting the heads cnc ported. That's what I meant was out of the question.

Aren't all Trick Flows CNC ported?
I didn't know they offered an as cast version.
At least when I bought mine they only offered 3 version's,
All were CNC ported
Just different spring/retainer packages for whatever Cam type you are using.

Yes they are ALL cnc ported.

Shouldn't you be able ootb make 550 hp with the right cam ?

Should be able to unless you found two ports back to back like I did. One went crazy turbulent.

The TF 190 head is CNC ported from the factory. 550 hp is within reach with a TF 190 as cast.

Yes sir! That’s the one. Anyone can reasonably duplicate this build slightly defined for the street by skipping the head porting and running a 11-1 compression ratio. The one thing that would be a big HP killer is not using a tunnel ram.

There’s enough head flow on the as cast Victor head to make some great power. 11-1 is easy 93 pump gas. The only single planes I’d use is the Super Victor ported or the Indy intake and probably have to pro ported. I’d make the Indy work.

At the magazines 376 CID, this can be closely matched via a 360 crank into an.030 - 340 for 372 cubes or punching out a 360 @ .070 over. That’s a lot but possible! Sonic check that 360!
Wooooooooo
