Cam help for 385 build.

Hello, I've enjoyed reading this forum for a long time and I finally joined. I usually can find my answer but this isn't your normal build. I'm building a 385 stroker (sleeper) and I'm ready to go to the machine shop. I'm needing cam suggestions because I'm trying to use a set of EQ235's with 64cc chambers and wanting to try and keep this as streetable as possible. I'm using KB135-040 pistons that have the 18cc d-dish. I have a couple of cams available the XE262H and Magnum 292H. The 262 should give a cr of 9.64/7.97 straight up or a 8.19 with 4* advance. A 8.19 might be too much for cheap gas and cast iron heads. Squench is at .043. The 292 will have a DCR of 7.32 with 4* advance. I thought of using Rhoads lifters on the intake side to give it a better 7.63 or more and with only half the lifter noise and possibly a little more lowend torque. This should look like a dual pattern cam at low end-282/292 and .504/.534 lift and a full 292/292 and .534/.534 on top with 1.6 roller rockers. Seems comparable to a lot of new style roller patterns. Exhaust are 1 5/8" huggers with a modified 2 3/4" collector flowing in 2 1/2" pipe. I'm using the early style Performer 2101 that the c-trackers use to call the "cheater" for hood clearance. I port matched it to a 1206 intake gasket, it looks like it'll handle whatever the 385 will ask. I thought the intake and headers would help out the low end. I know 235cc heads are a little large but I remember Chevy putting some 270 & 300cc heads on the 396. I'll adjust stall and gearing for the engine but would like a little fuel mileage. Thanks for your suggestions and comments!

best way to make those heads street able is to put a 440 underneath them,those heads can be ported to 340 cfm.We are talking 700 hp.not ported,you could build a 600 hp 421. either way,we are talking moderate or more solid roller motor

There is no reason for that head on a street motor. To get the benefit of the large runner size, you'll have to get into the 7-8k rpm range. JMHO
