Nope, I read it too.  If you read farther on the list the clip on aluminium
valve covers allow for larger lifts without hitting the stock valve cover
and added cooling for the heads...  Makes sense to me.

RIGHT! I'm sure the "Clip on Aluminum valve covers"  and the "Monza Single
tip resonator"  does a great job to increase performance!   Am I the only
one reading this list?
