valve seals wtf?

[crosupra]

i need new walve seals, but i found three types, and i don't know which type is for my engine because i made engine swap.

type I: http://www.trademotion.com/partloca...e=34&model=Celica Supra&year=1987&catalogid=1

type II: http://www.trademotion.com/partloca...e=34&model=Celica Supra&year=1989&catalogid=1

type III: http://www.trademotion.com/partloca...074&make=34&model=Supra&year=1991&catalogid=1

What engine did you swap into it?

 

[crosupra]

well that's the problem. it's N/A but i don't know what year.

I've been using the Viton ones supplied with the MDS Kits I use and they only spec 1 type to suit all.

My "guess" is they're all interchangable size and shape wise maybe different materials over the years?
