Ohton racing cool head o-rings

Recommended Posts

does it say cool head on it?  or like cool design head?  somethig like that?

 

i have one of these  no domes fit it  if you actually do get ahold of ohton they say that head is obsolete and worthless, buy the new one bla bla bla bla..  i think i just used pd o-rings on it or went down to the o-ring place and sized them all up.  

 

whats bad is at least the one i have is a decent design.  uses stock studs, and head sealing, dome support is pretty thick.  i ran it for a long time on a 350 i did.  it held up fine till the 7 year old crank let go and took out a dome..

the inner dome ring needs to be viton.  rest can just be good ole black o-rings.  it only uses a few rings.  mine was a 2 piece but the 2 pieces bolt together and it comes on and off as one piece.  it was actually a decent design whoever actually built it.
