Building heads before boost or bottom end

Default Building heads before boost or bottom end

So seeing that I have a spare set of heads and a collection of parts, I've been slow rolling on moving towards building them.

So far, my parts list includes:
JWT C2 cams
JWT cam sprockets
ATI Damper
RJ Manufacturing Oil Pump Gears
Super Tech 1mm oversized intake and exhaust valves

On the spare set of heads currently:
Supertech dual valve springs (unsure if on just exhaust side or intake and exhaust)
Custom VR38 Tomei Cam (I think 282 duration and 11mm lift, could be wrong, but it's aggressive). A million variables here...

The questions and concerns I have are:

I can spend $1000 and get a damn good hand port done.

Go broke and have the heads CNC ported.

The 1mm oversized valves might slow down air velocity and kill my low end.

Are the larger valves lighter or heavier than stock?

Getting the heads CNC'd will kill my wallet for minimal gain or loss of low end.

I build it with minimal work on the valve seals to fit the valves and assemble it with the JWT parts and have FOMO for not doing the port work.

Say F@ck the world, CNC it, maybe order stiffer intake valve springs, add the JWT stuff, the super tech 1mm valves, take as much time as I need to do it and throw it on my NA Z; Boost and build the bottom later.

I literally have everything. It's just paying the labor rates now. So I'm scratching and clawing step by step to get this far. Even if in the near term I don't make any serious gains, when boost is introduced, it will show a huge benefit in how much boost it takes to reach X amount of HP. It will reduce the delay and lag as the flow will be higher (Takes less time to reach 12PSI vs 15PSI). And even though most guys build their heads for crazy power numbers, I really just want to optimize my power delivery for my goals. I want the car and turbos to breath at 8k rpm, I don't want to max the turbos to reach 650-700whp, with a power curve that looks like a door stop and TQ that's as flat as Kansas. I don't need or desire gobs of TQ down low; but very consistent and manageable. This is absolutely not the most cost effective way to make this kind of power. I don't need built heads or cams to get there, it's just where I'm going with it.

Anyways. I'm just looking for thoughts and input on what I'm planning. Will i see a benefit before drinking boost juice or not? And for any of the old guys on here, you all know I tend to veer off and do my own thing and experiment. So I don't need people telling me it's a waste of money. It's my money and I'll do what I want.
