Len Hoffman has my 2.0 heads. He is repairing cracked plug bosses, converting to 12MM plugs, installing 8 new seats.
I am considering dual springs new chromoly retainers. The heads have new (expensive) sodium exhaust valves. Len doesn't recommend sodium valves with dual springs, he says change the to SS valves. So, should I keep the sodium valves & stock springs or go SS with double springs & new retainers? How much performance do double springs make? The engine is a fairly fresh 2056 with Dellorto 40's and a stockish Webcam. I have the parts to convert back to Djet but will probably drive it with the carbs for a while first. The car is a weekend fun car & not a daily driver. |

Always upgrade to a single spring with nice chromoly retainers. I have seen so many stock retainers fail that I no longer use them at all, same with springs.
The single springs that Len has are the same as the ones I sell/use and so are the retainers.. Stock springs and retainers are only good for stock cams, any performance upgrade should include better springs and retainers. Capn' I had no luck with their off the shelf grinds either, you should try one of mine one day- The only alterations are on the exhaust side of things and they work very nicely with D or L jet... Web cam does NOT build engines, probably50% of their grinds and the feedback on the TIV has came from yours truly... Cam grinders seldom know the best cam for your engine- |
