Yeah so I have a B20A9 motor, and I was wondering what is the best way to go with this motor while staying all-motor? I guess my real question is, what is the best VTEC Head for this motor, B18 or B16? And I would like to know what all this entails... Knowing that this is raising my compression, would this work with my stock internals? And would this lower or raise my redline? I need advice!

 

Anybody out there... reply if you have the slightest suggestion...

 

please post, someone.... I really want to get the most out of this B20A series motor...

 

Go with a B16 head. Better flow. Look ing my Sig for spec's of my B20vtec build.

 

The best head for most of your average street motors is whichever you can get cheaper, plain and simple.
I mean the differences are so slight, unless you plan on headwork and really seriously building the motor it really wont matter.
