couple hundred springs $200 new factory springs usually last at least 150,000
couple hundred fer valves $200 new factory valves usually last 200,000
resurface at my local machine shop $140
valve job $200
valve seals $30
Total is under $800 and I don't worry about valve seats, the only time they fall out is if the engine gets very hot and an eddy would do the same thing and they still need checked over by a machine shop first.
Good info...... I am going to get my heads redone with new springs, guides, seals, and hopefully better quality valves with hardened tips if I can figure out who offers them.
