That is for sure. Corky's rocker arms change will be interesting and I
cannot see anything detrimental to the engine by making this change, but
I too long ago learned to take auto parts mfg. claims of bolt on HP as
sales pitch. Roller rockers have benefits but a 20 horse bump is
significant.

I should mention that the roller rockers are the 1.8 ratio rather than
the stock 1.7 ratio. This gives better breathing and, according to
Morana Racing, an additional 20 horsepower.

Uhhhh...
I played rocker ratio games four decades ago. Unless things
have changed dramatically, don't bet the ranch on getting
20 more horses in your app per Morana Racing propaganda.
