RHS pump gas 360

We just built and dyno'd a 360 last week for a friend of mine who's a fireman locally.
I know there's some guys out there wanting to know how well the RHS heads we sell work on a typical 360 so I'm posting this for them.
Stock 360 block .040 over
stock rods with arp bolts and resized
KB 107's
balanced
IMM RHS heads, no porting
comp is 10:1
comp 275HL cam on 112 lca advanced 2°
stock pan
PRW 1.6 rockers
rpm airgap
Holley 750DP
1" open spacer
TTI 1 5/8 step headers
The carb is perfect OOTB with this combo. Witout the spacer it's a bit rich. Best timing was at 33° the day we tested it. It idled good at 900-950rpm and ran just fine on pump gas.
