Jay, let me know if you prefer me going in the vendor selection, but because I usually sell only in my builds, I rarely peddle parts and don't intend to
However, I have a customer who changed plans on a build. If anyone needs a set, I have an extra set of new, unused Trick Flow assembled heads, 1.46 springs, Part number TFS-56417001-C00
2350 for the pair plus shipping, no tax outside of Nebraska, and if you have cam specs, would blueprint them and document for the price. Additionally, can set up with your specific spring requirements if wanting to do something special for cost of seals and spring assemblies, but these are NIB assembled ready to go for most flat tappets.
