Questions & Answers
I Have brand new valves, springs etc. I also have original camshaft so can I install those in this new head
By Anon.
Yes, that's correct. These heads are specifically designed to work with all OEM components for any machine you select from our fit guide. For the money, they're actually really nice heads!
Does this head accept the stock valves, valve springs, CAM, rocker...etc.?
By Anon.
Yes, that's correct. These heads are basically OEM replacement heads without the OEM cost. They work with all remaining OEM cylinder head parts on any machine you select from our fit guide.
