That's actually a good street Cam & isn't too small for those Heads.
I just noticed the 70cc chambers so Cr. would be 8.96:1 with all the above specs. I wouldn't go any larger on cam Duration with that Cr. You would need to Mill the Heads or change the Pistons to raise the Cr. any higher.
I would also go with the Edelbrock Performer RPM intake #7101.
