I also have Comp 947-16 triple springs, with titanium retainers. All wishing 5lbs closes pressure, from new. Used only on the run stand. Changed configuration, and removed springs. They’re $400 for the set, extra. So $2500 for comlolete heads (minus rockers and shafts).
Paypal is accepted, however, you are responsible for the fee (4% plus 60 cents per transaction.)
