Using a properly set-up 194 head you will gain 1 point of compression & make more torque. Dont let anyone tell you different.
If you go w/a bigger camshaft your cylinder pressure will drop & therefore making your engine sluggish.
So if you are going to install a bigger cam, you always want to increase the compression ,so you will @ least have the same cranking compression as before & the simple way to do this, is to install a 194 cyl head.
