Hello everyone I have a problem.

I am now putting together a new block, and the head and block are ready to be mated. Well I noticed the the new block has a large metal plug where the crankcase vent hard line used to go into.

For reference this the line that goes from the block to the back of the "T" on the valve cover.

So is there another place I should for vac? I always thought it was needed.
It also should be known this is a race spec SR.

Any help or suggestions are welcome.

Pics for refernce

Stock hard line to back of T on the valve cover.

New block with the access deleted.
