Ditto Mark
After I added the one aluminium shim I find that its almost impossible to run the engine too hot. My 5port runs cool, idles consistant and makes exellent power in stock form. I now feel that modding the Go's is just abit too much. I rarely found with my 7 port that I was peaking out. Anyways I like the 7port in my truggy and 5port in my buggy.
I am not using a turbo head as I dont lik using turbo plugs. Always giving tuning hasles and doesnt last long. I dont feel the Go's really needs it IMO.
