I heard the spray pattern on the 39 lb Cobra injectors are not optimal for a LSx engine. They will spray the cylinder wall because they ar not designed for a 2 valve configuration. Can anyone shed some light on this before I buy a set?

You are correct, they spray in a 'V' pattern which is not optimal for a single valve configuration. Fuel will spray outward toward the walls of the port instead of on the back of the valve like it should.

Thank you! I'll go with the green tops then.

Yes, the injectors are designed for the type of head. i.e. single valve or multiple valve. Using this injector is not optimum by any stretch for any single valve engine.
