Which way to go? Thoughts??

Currently Im running a 427 forged motor, topped it with PRC LTX heads they have 2.165 hollow stainless manley in valves, 1.60 stainless ex valves, 58cc chambers, che guides, and 312 runners. No one has flowed a set on a large bore yet and it seems the info i can get is only on a stock bore which is

Lift Intake Exhaust

.2 151 117

.3 223 154

.4 265 200

.5 310 216

.6 349 229

.65 365 232

.7 370 235

Now that dont look to bad, i mean orginally i was wanting CID or MAST, but couldnt get any all were backordered. Anyway i now have access too a set of CIDs with their large bore setup they said the chambers would be 58cc, hollow stem manley bigger i think he said 2.2 in and manley stainless inconel ex valves, che guides, and they flow numbers when they tested on a 4.125 bore were as follows.


INTAKE EXHAUST
0.2 153 110
0.3 225 162
0.4 280 213
0.5 249 242
0.6 367 252
0.65 378 255
0.7 382 257

I can sell my PRCs to offset some of the cost as they are perfect. My cars making over 600 NA on pump now an im running a rather mild cam 230/242 630/620/116+4 that cam motion speced.

Do you think its worth it to switch??? I mean its hard cus we know what the CIDs flow on large bore cus this is from the shop that does them. The prcs its just a guessing game who knows what they flow on large bore let alone if what they claim on a small bore.

Thoughts???
