high compression heads are all different . I used a snyders 6-1 for years with 0 problems . I now have a 7-1 lion 3 head . much , much different from stock type heads (snyders included) . it requires much more fuel to keep up with the increase in air flow . less advance for safety (detonation) . I love the newly acquired torque !!!!!!!!!! and yes it gets out its own way quite nicely .........
just be sure you understand the heads needs . .....................
