had the F54 block re-honed and painted with brass freeze plugs installed. the head just got a simple valve job. the stainless exhaust valves i had were too big for the E88 but i was able to use the stainless intake valves.
what i have for the new build = new water and oil pump, AZ Car baffled oil pan, ZX dizzy, MSD blaster coil, 6-2-1 header, mikuni triple 40phh carbs, trw timing kit, E88 head, flat top pistons, new bearings and piston rings. having these things powdercoated: motor mounts, cam timing cover, valve cover, alternator bracket... more but can't think of right now.
