Just a refreshed redtop head. jwt s4hl cams, springs, retainers etc. Pistons are 87mm.
In case anyone ever builds a sr bottom end. Mazwork offers their hg in sizes ranging from 86mm to 87.5mm, then it jumps to 90mm. Don't be like me and order 88mm pistons because then you will be stuck running a crappy cometic hg. I had to send the 88's back and order up some 87's just because I wanted to run a better HG. The head gaskets that mazwork sells are made by apexi for them. At least that's what mark the owner told me.

Here's a drifting video of some dude absolutely shredding the track up running a 7163.
