Gen III and Gen IV block differ primarily in the form of the reluctor tooth, 58X for Gen IV and 24X for Gen III. I believe the camshaft position sensor is relocated to the front timing cover as well. Some have AFM and VVT, the L76 shouldn't have VVT IF in the G8, the truck versions do have VVT L76. More info here.

As far as 215 or 225 or 230 being too big for a 402, not even close.

Back to the thread, so these 230 V2's are the exact same price as the 225's?

Yes....essentially the 225's are no longer available. That product has been superseded by the V2 230's, the same as the 205's have been replaced by the V2 210's

The 215's were essentially our first V2 product and the current roll-out of the new 245's are the larger cathedral V2 port design.

Hope this helps clear this up....it seems to confuse alot of people for some reason

so the 230 v2 heads come in a 72cc chamber? No other size available? They need to be milled to 64 to keep my stock ls2 compression?

Tony Mamo @ AFR

62cc and 72 cc.....just like the former 225's.

We can mill the 72 version to exactly what you need or for a bump in your compression you could just opt for the 62 cc head perhaps.

Great results!! Of course, what else would we expect from Pat and Tony? Looks like some LQ4/LQ9 swaps are going to head this direction as well.

Good stuff! I'm a bit disappointed though. All of this time, energy and effort for the L92's...WASTED! Sometimes, we MUST go/get back to the basics. I'm sure the cam choices for the 230 heads are more than abundant, unlike the finicky L92 heads, huh?

Tony, what size (lift, as well as duration and lobe separation) camshafts do these heads like?

I wouldn't call it wasted. They just aren't understood near as well as cathedral ports.
