a mate at school offered his brand new flattops to me for $100 a while back, was thinking of getting them but ya need to bore out ur head and stuff dont ya?

na no boring out the head the only thing that really neccasery is valve reliefs but someties flat top a series pistons are just normal wones shasved down with out dish
wat head are you running and wat block

79mm bore in an a14 will take the cc out to =1509cc
79mm bore in an a15 will take the cc out to
=1607cc

wonder wat compression ratio these would give

pity one is broken..:(

could have been a good set if it wasnt broken.....now could it be fixed?

So you two blokes are in school and not one of you can spell? Well thats a bit of a worry for the Australian education system isn't it?

Thumbs up fellas.

One piston is broken...

I wouldn't think it could be repaired. Probably worthwhile getting a replacement.

are we all psyching each other out..???
I would give them a crack if i wasn't broke still.. :(

Well they seem like quite a good deal but I didn't want to go boring out my block, save that for the next rebuild in about 20 years
