318 heads on a 360?

I'm building a 360 for my '71 Swinger.  Its 0.040 over with a .477/.480 cam, 4 bbl & headers.  Currently the car has the original 2 bbl 318 and I just got those heads rebuilt a few months ago.  They got all new valves, seats and bronze guides.  I'm wondering if I'm on the right track if I re-use these recently rebuilt 318 heads on the new 360.  The 318 heads would need better springs to handle the cam.  But I have some good springs.  So I'm thinking 1) spend another $500-600, maybe more, on some 360 heads (I have a good set of castings and a second set with good springs and valves, I would get them decked and assembled and I might do some mild porting first) or 2) swap out the springs on my good 318 heads and mount them up.  Won't cost me a thing.  Has anyone put 318 heads on a 360?  How'd it work?  I'm intending this car to be a fun street car that sees some track events.  Thanks.

Re: 318 heads on a 360?

I have a 69 Coronet 318 2 Barrel that I'm looking for someone that is familiar with this motor or has any mechanic recommendations.  Recently replaced the timing chain/gears and then changed the distributer to a electronic system.  Before we went to the electronic distributer kit, my plugs were getting fouled and wasn't getting any spark. After changing, I'm getting spark, but can't get it to start.  Looking for some help.. In North Arlington area.   Thanks

If your plugs are fouling, it's more likely a fuel problem rather than an ignition problem.  Make sure your carburetor is well adjusted.

TJay have you tried pulling the distributor up a little and turning the rotor 180*. It is possible to get the timing off by 180* because the TDC mark comes up twice in a firing rotation.
