A little use of Google will be usefull. HYDRAULIC ROLLER-Great mid-range with superior top end power. Needs programmer.
1300 to 6300 rpm XR269HR 269 273 216 220 .525 .532 114°
It's a small cam that will give you a stock sounding idle (no lope) and about 20 RWHP gain. For your question about the 66cc vs 64cc heads, the bigger heads will have a lower compression ratio (good for Turbo/SC).

216/220 .525/.532 114 +4 is your cam specs. 66 chambers will lower your compression compared to the 64. cam will have an idle(slight chop).

This cam with 1.8 rockers can perform
My car has done 11.4/118.6mph so far at 3625lb with this small cam. Plus heads, 25% and BBK on LS6, and short tube 4 into 1s, 3.73 and SS3600
Dynojet rwhp about 418 so far.

Aiming to gain another 30rwhp from Ported Fast and Long Tubes.
