Please help me figure this stuff out

[1967formulaS]

Ok, so I need some help figuring out cam and head choice.
Engine:
440 bored +0.30 - motorhome block.
0.019" TRW forged pistons down the hole.
Scat forged H beam rods stock 6.760"
Forged crank - stock stroke
Ede victor 440 single plane intake.
Msd 6Al ignition
Bits I have:
Choice of 850 vec sec holley or 1050 dominator.
Choice of 516 or 452 stock heads and stock rockers.
The car:
67 fastback barracuda in full Street trim.
18 spline hemi 4 speed
Dana s60 with 4.3 trutrac
275/60r15 rear tyres
15" skinny"s on front
Competition eng adjustable shocks all round
Still have v8 torsion bars and v8 rear leaf springs

What I would like it to Do:
Run in the low 11"s

I intended to run the Trickflow 240 heads and a solid cam but funds are tight, so that's on the back burner for now.

Which heads would you choose 516 or 452?

Solid or hydraulic cam?
Crane. 680201 has been suggested - will this work with my heads.
Or a 509 mopar cam.

Is getting into low 11"s achievable with the parts I have or am I dreaming?

Will a set of 1.6 rockers help?

As always, your suggestions are appreciated.

The cam choice will be affected by the gearing. I've ran the 509 withgood results. I'm not as familiar with the other cam.
Dominator carburetor? May be too much for the engine size. The 452 heads will outflow the 516s. There is about 5/8 of a point of compression difference between them, the 516/915 having a closed chamber and more squeeze. The head gasket thickness was also left out. It is critical in determining the compression ratio.
Most of the build looks good. I'd consider subframe connectors, an 850 Holley, a .027 Cometic head gasket to maintain some type of quench and the 452 heads.

Thank you. That makes sense.
Would i need to use 1.6 roller rockers with the 509 cam?

Can you deck the block .015? If the finish isn't good enough, cometic/MLS gaskets are not recommended, so this might be something you need anyways.

I would recommend the 452's, they're pretty easy to port. With a Serdi valve job for 2.14/1,81 SS valves and my first porting efforts, 69.7/.100, 141.6/.200,197.7/.300,231.2/.400,240.9/.500, 244.5/.550 where they stall, but no reversion. That was my amateur first effort, my next set went 265/.550. That's with almost exclusively bowl and short turn work and a good valve job, and not anywhere near a "max effort" because it's for an endurance application and I don't want to go too thin anywhere nor increase runner volume significantly.

you'll need a pretty tall cam to get into the low 11's.
