My seat of the pants testing was against friends cars that went to the race track on a regular basis.
Before & after the 194 head install tests were done against friends cars.
The compression was raised also going from over 10:1 to 12:1.
But even with that compression gain & a so called worst flowing cylinder head, my car was definately faster than w/a large chamber head.
I would bank on proven cylinder heads, like from Mike Kirby & Larrys 194 head. Compression really wakes up the little six.
My car went from 14 second car to a mid 13 second car w/the 194 cyl head I used.
