Hi threedogs,

good point about the lead effects on wearing down the valve surface and even another parts of the engine (supposedly all internal parts of the combustion chamber). Obviously there is no justification on using lead due to its healthy consequences, but might be worth then to use some kind of substitute... especially because my engine is going to be soon 340.000,...

I bought this GU second hand. I paid 8 grands so, not bad at all, especially when is said that this TB45 are very tough. The rest of the car is pretty well it needs some after market replacement, but for sure in the same way that a new car... and at this moment I have a lot of fun with the project itself.

Thanks for your replies.
