Got three heads leftover from a big batch i just did.
1 perfect cond. 50cc puch hi comp from treats
1 70cc puch with o-ring groove. I might be able to find an o-ring, not sure. Relatively low compression, a modified version of some treat head.
1 50cc batavus M48 Laura head, decked about .025
all are cleaned and blasted, can be painted with 'nano-ceramic' hi temp for an additional charge.
email is best, i dont check buy/sell very often. I'll do some pics below
