[Healeys] Thoughts on my engine

[Curtis Arndt]

Understand, but with a proper Aluminum head you get a great bullet proof
head that double the power band.  Normal power band for a stock BN1/2 is
2,500-3,500 rpm. With the Al head the power band goes to 2,200-4,200 rpm.
So wrote Mark Lambert in his testing over 20 years ago.
