I have a similar 318 build with 8.7-1 compression, 2.02 J heads, and I used the Comp Cams XE268 that has similar specs to yours. I installed it 4 degrees advanced and it has excellent low end performance. Out of steam by 5500 but that’s ok. Just make sure the valve springs are spec’d to the cam, or even a touch stiffer, and she’ll be a ripper.
