Default It's Hybrid Time for me Bugeye, but ?'s

I had always planned to go to a 2.5, but recent low compression test results (135 in #1 and #3 and like 23% and 32%, 2/4 were 150-152 12%/8%) have me accelerating my plans I am going to do a 2.5 STI SB Hybrid with OEM WRX heads.

Car runs great, but I don't pound on it much, or maybe I would have broken something by now (had from 15k-75k)? Just figured if I was to try and use my heads, I might as well do it sooner than later.

My questions are around what other changes might make sense while we are there and would best add to my set-up/new engine? I do not have too much budget to go beyond the block, head studs, gaskets, labor, etc...and am already leaning toward a new clutch.

Purpose: DD/2-4 autox/yr.
#'s: 288whp/278lbft @ 18psi 92
Goals: 295/295 - 310/310 range + low-end torque gains

Bits that matter: 16G(550cfm), FMIC, 860cc Inj, Walbro255, 3" tbe, STI up, CobbAP (PDX)

I am not considering plans that include P&P or heat wraps, my goals are modest and I just can't spare the extra $s vs other things. PDX Tuning will be doing the work to include the usual cleaning, etc. plus the new map.

What I am considering:

1. Clutch (original OEM is 75K, might as well) - OEM replacement or similar
2. Gruppe-S Unequal Headers - $350 (HKS would be 1st choice, but too much$$) - worth it or no? 200rpm+/- better spool? Addicted to boxer sound.
3. Lightweight Pulley - just not sure of real benefits, but for this set-up?
4. Engine mounts - replace OEMs for good measure

Comments on above or anything else that would make sense to consider?
