It seems like the cathedral port heads flow much better on the exhaust and the l92's outflow on the intake side. Given the fact that I am pressurizing the intake with a blower, does the intake flow matter as much as the exhaust, especially since the EFI intake manifolds on both options are the bottleneck?

The two aftermarket heads have a thicker deck surface than the L92's. Very important in FI applications.

Seems like you cant go wrong with the TFS' around here lately...

I'd go with a nice thick aftermarket casting for forced induction. Look into certain heads like the All Pros or ET heads that have the dry deck design.

More intake flow = more power, more exhaust flow = more power, which one will have a better effect?

Blown I would go with the thicker deck head that has better exhaust flow, with close to the same intake flow as the cnc L92.

I loved my AFR heads with the 3/4" deck thickness, too bad they don't make a higher flowing head.

The cnc L92 heads are awesome, but there are better heads out there, check out all pro's site and ET's site, see what you like then give both a call and see who's got the better deal and what's going to work best for you.

I like the ET 265's

LSW 12 Hurricane heads from allpro are pretty nice looking too.
