BP26-10-271 is the gasket you want.My understanding is that the earlier head gasket is recommended, but so far I haven't heard of any vvt head gasket reroutes melting engines.

Frohock lost two vvt engines with reroutes and the later head gasket.
The engine's not in immediate danger of blowing when you run a reroute with the stock gasket, and Frohock's engine losses can't be definitely laid on the use of a reroute with the later gasket. And, Emilio now says a reroute can be used on a VVT engine with either gasket.
Which gasket did they run on the VVT engine in Crusher, when they won 25 hours of Thunderhill? And also in William Bell's car in that race? BP26-10-271. That I think says more than any other miscellaneous data points.
The later gasket blocks some of the front coolant holes to force more coolant to #4. You add a reroute pulling coolant out of the back of the head, IMO, you can easily starve #1 now. Or, rather, if your cooling is marginal, #1 is then at risk.
