48degree blocks and heads

I understand. When I move up to an R3 block I plain on having another cam made like the last one. Still having a hard time finding a core with the 4&7 lobes swapped but I'm hopeful. And yes from my looking 48 are more plentiful then 59 R3 blocks and cheaper. The new aftermarket blocks that are not made or actually sold by MP/direct connection are still about a year away.
