Hey guys,
In the quest for upgraded valvetrain for my h23 head, I've come across a few different sources that sell 1 part number for both the b18a/b (sometimes b20b too) and the h23 head. Honda doesn't use the same part numbers, so I really don't know how else to cross reference the parts. Does anyone have a stock seat, spring, and retainer from said motors that I might be able to have or get really cheap? I'm curious if this really does swap. If anyone actually knows, that'd be better. I don't want to go raid a car at the junkyard.

I just ask because I'd guess there is more support for the non-vtec b-series than there is non-vtec h-series. Speaking of which, any recommendations on valvetrain if this is a feasable swap? My cams have .410" lift and 276* duration and my goal is a 7500 rpm redline.

Thanks,
Burt

have you ever looked at the 2 heads side by side, its funny, the are almost identical.

im not saying they fit or anything, but i have seen the same thing (companys using the same part number for both)

No, I've never actually looked at a b18 anything. Or for that matter any b or d series motors. All the b-series I've ever seen are VTEC ones that have 20+ pounds of boost crammed into them or are completely stock.
F and H motors are what I deal with since I have preludes and an accords.

Actually, I take that back about never messing with B-series stuff. I've had to deal with the b20a/b21a1 from the 88-91 prelude that has absolutely nothing to do with the b-series the rest of the honda community uses.

heres a picture of my head (with a junk header) crower cams and rocket single valvesprings




and heres an H23 taken from JG's site



very similar arent they ... only thing you need to worry about with the valves is the stem length/diameter i bet....
