Review on Edelbrock 5703 Sure Valve Spring by Don Devine

Revainrating 4 out of 5

Ideal drain replacement for Eisenkopf LT-1 engines.

These are perfect for refreshing the LT-1 iron head in my 1995 Caprice. These and new valve guide seals breathed new life into the high-mileage production engine. I'd give them five stars but they've been in the car for less than a year and I'd rather wait and see if they handle sub-zero temperatures better than the last three hives.

Pros
  • Replacement parts
Cons
  • Slightly torn
