Hi can anyone tell me the make of these rockers 1.8 ls1 they came in our engine that was built for 24hr le man racing the motor was pretty bespoke before we changed things originally had 243 heads with 350 block big springs now we have changed heads but some of the bolts are a bit rough.
any help is appreciated .

 

I’d guess Comp or Crane. You don't have any other photos?

 

I was thinking the same I will get some more pics now

 

They look like Crane "Quick Lift" rockers (see photo below)

 

Yes we think so also
