well im thinking of getting either the mugen or spoon when i pull off the head of my b18c to upgrade my valve train , anyone have one these on there cars any problems , i would like to bump up my compression a little with this
Here you go
I had my Spoon 2 ply on my B18C, bumped the compression up from 11.1 CR to roughly 11.4-5 CR. Off the line the throttle response is a bit crispier, and you can tell running on 91 octane, the car pings slightly at low rpm especially with load.

I installed a Mugen head gasket on a 98 ITR with full JUN setup. bumped his compression up to 11:1 from 10.6:1. Made a huge diffence and no problems whatsoever running on 92 octance. There’s not much of a gasket though. Take a look…

wow very thin gasket, nice pic thanks for the info dan
