Add to additive?

[08z06]

2008 Z06 Corvette. As You may know this engines (LS7) have valve issues. My heads have been "fixed" about 5k ago. I have been running a few different additives in it for the last 2 years.I want to be proactive and keep thinking a better gasoline would maybe save my valves.TCW3,Redline si-1,Redline Lead substitute, and just started using "race gas" octane booster at a low mix rate. Can I mix all these together and create my own blend? Anybody do this?!!!!

I would think once it's fixed because of bad machining in the first place it would be good to go.

Nothing you do will prevent defects all this does is kick the can down the road.

I agree with oldhp. Have you heard of fixed heads having the valve problem return? How is the problem being fixed in the heads anyway?
To answer your question, yes I have mixed various additives but not specifically to address a valve problem, just for preventive maintenance and just on the small engines (mower, dirt bikes, etc). For example, in the dirt bikes gas I usually mix lead substitute and Lucas fuel treatment... sometimes an ounce of Sta-Bil if we are approaching winter storage. Never had a problem.

I wouldn't recommend adding to additives like that, but it could work. But if you add additives like that, it could make it to where it cancels out the other additives and then they won't work in the 1st place.
