FS: 035 Heads with Dual Springs
Long story short is I have a set of 035 Heads that where purchased used back in 2008. I never installed them on my project car as I found another set that worked better for my needs. I do not remember how many miles where on the heads but they do have some nice parts in them. I had them professionally inspected so I could list all the specs for you.
64cc Combustion Chambers
Upgraded 2.08 Intake Manley Valves
Upgraded 1.60 Exhaust Manley Valves
Dual Valve springs with Titanium Retainers (possibly Patriot Gold or Manley)
The do have O-Rings/Fire Rings machined into them I had planned to have these machined out before sale. I wanted to post these for sale first so you could choose your desired Combustion Chamber that would work best for your situation. I was told they should seal just fine with the rings left in them if running a GM MLS gasket but I would suggest getting them milled first.
These heads normally are great for boosted applications but since they have been milled before (originally 71-72cc) they will be better suited for NA or Nitrous.
Sale price is $675 shipped. This includes being professionally milled to your desired CC below 64cc.
I tried to include all the info I could think about, if you have any questions please let me know.
