I was the last to chime in on your last thread so I'll be the first here. I'm currently building the 445 survival kit, am using a 750 vac sec Holley (3310) performer RPM intake and the same 60069 heads. My ignition is MSD 6AL and I'm running Hooker super comp headers. Pretty much the same stuff you have on the shelf.
I have long passed the point of deciding on the stroker prison break 445, it just makes sense. The RPM range you are talking about is right in the wheel house. If my cam (comp XE274HD-10 1,800 to 6,000 rpm range flat tappet) doesn't work out I'll change it, but for mainly angry street duty I think it will do nicely. You mentioned hydraulic rollers, your 60069's are flat tappet hydraulic recommended only at .600" max lift. Edelbrock makes pn 60065 that will accommodate .700" lift with dual springs, they sell it for hydraulic roller setups. Near as I can tell you will add a grand for the roller lifter and rocker setup, my wallet said whoa for now
. I did some careful searching and can say with "reasonable confidence" that the only difference between the heads you have and heads that will accommodate a roller cam is a spring change, but take note of that. The heads you have still require careful setup with the right valve train geometry. Adjustable rockers are necessary to get it right. Pay close attention to other threads here that speak to these issues, there is some great stuff there. One of the things that was killing the 390 in my car was poor valve train geometry, need to get that right (again, tons of knowledge on this site from members in this area!).
Think it through before you pull the trigger. There's a lot more to say and all of this has to be filed under JMO, but it is the beginning of my two cents. More later when I get mine on the chassis dyno. In the meantime, cubic inches rock
