Cylinder head decision for 318

Whiplash cams are great. they DO what they are advertised to do. That said, they STILL benefit from raised compression, regardless of what the description says. Added duration ads up to needing more static compression. Although the tighter lobe separation and the BIG dual pattern split helps, it's just a band aid for higher compression. That doesn't mean they are bad cams. They WORK! But putting one in an engine with less then 8:1 compression and expecting miracles is a stretch.
