I think Guy is correct, and if it was timed at 102 degrees we know why 
there is intake valve interference. The cams I've used had recommended 
timing at 110 degrees ATDC. With the 948 we advanced 2 degrees and 
that's a long way from 102. Typically the cam will retard as the chain 
wears, so it may have been incorrectly assembled?
