RIVA DOMES & HEAD quick question

[orangefinger]

Its a 2 part Riva Head which was on a 62T 701 the domes indicate 35cc and 84mm, does this mean that domes are up to 84mm or are these 760 domes ? What should the Domes yield on an unported engine at sea level , 180 PSI ??

Any advise appreciated

Thanks

if you have calipers you can measure it.

84mm domes are for 760 motors. 180 is a fair estimate for a 760 with 35cc domes.

 

[orangefinger]

so if it says 84mm 35 cc its a 760 dome ??

 

[orangefinger]

help ??

The Riva 35cc 81mm dome should have around 185-lbs compression for the stock bore 61X cylinder.

Riva domes are marked on top with 81mm for the 701 engine and 84mm for the 760 engines and have those exact measurements unless they have been machined larger.
