Can any one tell me how much differance there is between a D16A6 w/t a z6 head and just a normal D16Z6?
Is there a power diff? or anything?
The reason I'm asking is because a can get a D16A6 and swap the D16Z6 head on to it for cheaper, but I don't want to spend money on a swap and still come up short with power.
Thanks for the help

 

im doing the same thing to my civic. a6 bottom, z6 head. supposidly you get gains of 20-30 hp and also a a6 bottom with z6 head makes more compression then a regular z6, so i am told.

 

Can anyone else conform this?

 

this is where i saw it, these guys give a better explanation.
