The Sunbeam Stilleto and Singer Chamois versions were tweaked with carbs, head mods (I think) and may have incorporated a different cam and therefore double springs.
Fitting a set of inlet stem seals will do no harm a all .. I expect they are steel guides pressed into the alloy head.
The engine (as you are probably aware) is derived from the old Coventry Climax engine .. so there are going to be a lot of variations. You know .. the RAF even use that engine in their low armament loaders. They were always repairing them! Long time since I worked on or drove any Imp, Chamois or Stiletto : )
If I were you, I'd ask one of the club folks.

Oh happy memories!! Removing the engine and transaxle with a jack on a roller skate! Health and Safety...pah! Not surprised they had cooling problems...27 feet of hose if I remember correctly. I used to borrow my mates Imp. We had a racing exhaust, twin carbs and a racing head on it. Beat the pants off a Porsche up the M40. Most common thing we had to do was change the speedo cable, 'cos when it hit the peg at 90 it broke! I still think the best feature was on a nice summers day bombing down the road with the rear window open and acting like a rear wing!
