Blake, I did this mod years back on a 1220 bored 1098.. IF you use a STOCK cam and the ex seats are worn and the head hasn't been skimmed and you never over-rev it, you `could' fit it straight on. But I wouldn't take the risk. Too many IFs... BTW you MUST use a 1275 gasket. BK450 is best. Anyhow, full details with dimensions, of how to pocket it are in Des Hammill's book `How to power tune the BMC/BL/Rover 998 S series'. $39.95 from www.pitstop.net.au PM sent.

hey doc, will have a look at that book, ive been doing quite a bit of reading VIZARDS books lately, im going to go all out on this motor and do it right the first time through, (hopefully!) plans are to have a GR cam to suit the blower, maybe some of you corolla highlift rockers, and hepolite pistons, (if i can find em!) also been looking down the the NOS rd, just a 30hp shot should do it! just for the dyno days and 1/4 mile sprints, (thats just a maybe!!!) blake |

Best 1098 pistons now are Hypatecs, but were none about a while ago. Very hard to get good UK pistons for a 1098 now. KC even got Hypatecs sent to UK! 
Depending on the bore size, I may know where there's a set of NOS pistons in BMC boxes...
