Hi,
I am starting out on a 1380 build and was planning on using the BK450 gasket which has proved successful on my smaller bore build.
Measurements of old gaskets between the bores look like the min diameter is 72.8mm (although round section of the gasket is 73.5mm) . This looks a bit marginal even allowing for a 0.6mm smaller diameter at the top land and also the offset boring

Has anybody build an engine with a deck height of 0.010" or less with this gasket? Was there any contact visible?
Thanks

Joe C

I have, with a deck height of about 5 thou and no ofset boring I didnt see any evidence of contact with a red line of 7k

I know it is generally accepted to offset but is it safe not?
Without offsetting it should be OK on the measurements I have taken

Pistons are never the same size as the bore and the crown is usually smaller still so it shouldn't be an issue

 Is it A-Series only? I think it should be...
So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'...
