The Windsor Jr. heads are a little under sized for a 357. I also think you could use more cam lift and get at least your exhaust duration at 50 up into the 234's. Your at 228 right now. I'm not a huge fan of single pattern cams. You might also look into a long tube header with 1-3/4" primaries. The best head IMO for the lift your running would be the TFS Twisted Wedge, but you would have to get them drilled for the 1/2" head bolts. Second I would choose the AFR 185cc heads. Don't forget to check valve clearance! If you could post your dyno that would help more also.
Thanks
