So I picked up an already built 505 off here. Its a 440 block, Eagle stroker kit, has Indy EZ-1 Max Wedge port heads with I am told are as they come from Indy springs wise, and for a cam it has the old Mopar .590 in it 4 degrees retarded.
Its going in a 67 Fury Police Pursuit car I picked up last year (the block is actually a 67 within a few days of the cars build date) and I want to have a hassle free large amount of street miles drivable car as well as occasional strip use. I have much faster cars for strip use already, this is my "cruiser" lol so I am willing to leave a fair amount of peak power (but not too much) on the table in exchange for a fairly decent idle, fairly low maintenance rocker adjustment and valvespring life wise, enough vacuum for my power brakes, etc. I recently went with a street/strip converter in the thing like a 2500-3000 or so stall, a mildly built 727 from Keith Long, and I went with the factory original 3:23 gears and a nice sure grip setup from Dr. Diff. so I do not want to change any of that.
So what I was thinking was I went out and got the dual plane indy manifold already and will open that up to the MW ports, and I was going to go with an 850 or 950 4150 carb. I was looking at going with a much more streetable and lower maintenance cam either a hydraulic or hydraulic roller with around 250 duration at 50 like the XE295HL Comp Cams hydraulic (251/257 duration at 50, .564 lift) since everything I am seeing points to the .590 Mopar being too much duration for me, much bigger stall requirements, and frequent lash adjustment. As far as the springs I have no idea - all I seem to find is that the heads have springs "good for .600 lift" in em. Would these be decent for a hydraulic or hydraulic roller in the mid-high 500 lift range? Anyone know what specific springs these heads come with?
Looking for input basically what do you guys think or recommend?

Also, I was going to go with the TTI 1-3/4 primary C body headers and 3" exhaust. Compression works out to around 11.5 to 1.

Hrmm those are a single spring with damper. What Ive got by eye is a double spring with damper...
With the new hydraulic rollers they can just be used as is right? No need to bush lifter bores or any of that like a solid roller? No super high spring rates?
Like I said Im leaning towards a regular ole hydraulic do to friendly spring rates, cost, ease of maintenance, etc. If the hydraulic rollers are better and still streetable springs and no need for machine work I would be in...
Keep the recommendations coming!

I bought my EZ heads direct from Indy at a car show and my heads have comp 928 dual springs with damper rated to .650 lift.
I had a shop look the heads over and they tested the springs at 160 pounds seated (1.925" installed height) 335 pounds 500 lift and 380 pounds 620 lift and coil bind at 1.150 (775 lift).
'68 Coronet 500 w/ Indy EZ-1 headed 446, 727 trans, 9" rear First day at the track with SUV street tires and no traction: 1.688 60', 7.24 @ 101.79 in the 1/8 mile
