Cyl head hydroblast.

[Johnh]

Has any body had an ally cyl head hydroblasted? Will be doing a full top end overhaul soon.. the head has been ported so was wondering how hydroblast would effect and if I would have to repolish ports.. I have seen some results forum hydroblast on other parts such as carbs and was surprised with the Finnish.

Members have been known to clean them in rhe dishwasher! You just have to get the duck oil / GT85 / WD40 on quick due to the salt in the tablets.

I had a K series block done (don't have a dishwasher!), although the appearance can change to more of a satin look than shiny, the sealing surfaces etc were just as smooth as before. I can't imagine it would have any negative effect on your head. Pic in this thread: https://www.lotus7.club/forum/techtalk/liner-heights-took-far-too-much-block
