Just want to clarify a few things... I decided since I'm doing the all-motor thing with my B16, I should at least start with a head with decent flow characteristics.

1. ITR head obviously flows better. And my Skunk2 IM and DC 4-1 will bolt up no problem.

2. Are there any oil lines that need re-drilling? I assume not.

3. What will be the compression difference with the ITR head on a B16? (Stock Bottom).

4. OT: Going rate for used ITR heads (bare or full).

Thanks in advance...

 

the heads are basically the same. the itr one is just slightly ported from the factory.
