Thanks for your help. I have a 85 CRX with a single weber carb. I cant locate any numbers on the block, where should they be??
The head is from another engine, it is a 16 valve head with a 12 valve cover installed on it. How do i find id numbers on Head??
I bought it not knowing all these great details.
First i want to find out if this combo is decent, runs good but not much power. Mileage is about 25 mpg.
Would like to get it set up properly to run better and stop minor leaks from misfit valve cover, or change head.

On the outside this car is exceptional, if it werent i wouldnt care.
Thanks
