Nick,
Your caveats re the need for heli-coils duly noted. However, you cannot make
the following statement and not elaborate..........!
>But, the aluminum head made all the difference in
>performance.
In what way "all the difference"? More power? Better fuel economy? Running
cooler?
And what were you comparing to? An old, tired, stock head desperately in
need of a valve job or a nice, fresh stock head?
Enquiring minds need to know.............
