EQ Heads and stock rocker arms?

Great post and very helpful information. But it has me sitting here looking at the pile of engine parts that I've collected over the past 10 months and am about to begin assembling. Here's my combination of parts and I'm pondering any needed changes. Open to any and all advice. Long block is a 340 +.060 over with KB243 pistons on factory rods and balanced forged crank. I have a Lunati VooDoo Cam #102000704 with specs listed below.
I just picked up a set of Hughes EQ Heads that came with the 2.02 Stainless valves and 1110
springs. The previous owner of the heads had them cut .040 which makes things a little
tighter in terms of piston to head clearance since the KB's coming out of the hole at .018 topped off with a shaved closed chamber head. My (non-professional) calculations tell me the a set of Celtic .060 head gaskets will regain the safe space needed for this combination? (Looking for experienced input here). Once assembled I will of course check all clearances.

Next close spec I'm looking at is the cam and spings combo. The VooDoo cam is at .547/.569 @234/242 respectfully using a 1.6 Rocker. This lift is slightly over the spec of 1110 springs of .550
If I use a 1.5 rocker I would fall just under the spring max at .513/533 With that said, I am cautiously leaning towards a 1.5 rocker yet reluctant to give up the added lift of the 1.6. Hughes spring spec also lists a coil bind at .620 which I'm thinking might allow me to run the 1.6 rocker?
(Looking for more experienced input here).

The rest of the build includes an AirGap with Holley 750DP, 727 trans with manual valve body (converter TBD somewhere between 3000-4000) 8-3/4 4:88 on a spool. The application is an
A-Body 1/8th mi. track use only. Hoping for 400+HP and a low 7sec ET.
