What about a Crower 60211? Seated seat pressure looks ok with the 68404 springs even though Crower does recommend the 68405 springs. I know my unported heads will not take advantage of the lift but possibly better overall than the 041 clones. The 108 LSA might make for a little lumpy idle and higher power band.
