Had an extra head ported for my project. Claimed to be the highest flowing head available outside of a welded up angled intake port. Had a hell of a time getting the item back from the shop. Finally got it back and it comes with new stainless oversize valves and single valve springs on each valve. Has anyone had experience with single springs versus the twin springs that most builders use. I asked for titanium valves but was told they were out of stock. Did the builder mistakenly install springs for titanium valves? Contacting the builder is out of the question.
