Who is using an oil deflector under the intake?

44 years of racing and I never had a lifter pop out of the lifter bore. Do your homework while the engine is being built prevents issues like this.

I'm just relaying what I've heard. I saw someone post about it and they claimed it saved them. Nothing wrong with an extra safety net. I know I'll be buying one because they're cheap, quite possibly effective, and look neat.
