Quote: Are those longer valves than Victors come with normally, or did you figure out the right retainers and locks to raise the installed height that much?
I looked into running longer valves but the cost was prohibitive. The retainer clearance is going to be subjective to the rocker arms you are using. The Hughes 1.7 ratio rockers would clear some of the smaller diameter 10 degree tool steel retainers and the light weight super seven Manley Tensilmax retainer. Again that was with a .030 shim. I needed .090 worth to get the sweep pattern tight but the roller was running off of the valve tip. Also the .090 increase in rocker stand height opened up a ton of retainer choices at 2.00".
I am going to run Manley or Xceldyne light weight titanium retainers, Manley super 7 titanium +.050 locks and Xceldyne .040 BeCu spring seats. The Isky 9999-RAD installed height is 2.00" as well.
