If this truck is a street driven daily driver, then you will be much better off with C8VE, C9VE or D0VE heads. The D0OE-R casting you want to use will be a mismatch in such an application and you will not reap their benefits unless you run the CJ-headed 460 at 5500-8500 rpm.
The ports are so huge in the SCJ heads that the intake port velocity is lazy as hell when they're mounted to a 429 or 460 that is run at normal operating rpm's. Conversely, the alternate heads I mentioned above (when set up properly) will offer far better throttle response, better low & midrange torque and also give the CJ heads a run for their money from 3000-6000 rpm. These are truly a better overall cylinder head for a 500HP street driven 460.
If you are building a 521 stroker motor or a super high rpm 460 screamer, then the above info would not apply and the CJ heads would be a better choice.
