DIY head porting question

I have a question concerning the casting for the rocker arm bolts in the runners of the lt1 heads.

Can I smooth those out and if I were to poke through and reach the threaded hole for the rocker stud would this cause an issue.

For example, I have this going on.........

And was wondering if I could do this...................

I am thinking a thread sealant on the rocker studs would stop any vacuum leaks, but I am just looking for some second opinions

Thread sealant on the rocker studs is actually an OEM practice, so you'll be fine.

Also, PM sent.

As stated above. Just use a good amount of thread sealer on the rocker arm studs and youll be good to go.

What type of thread sealer would be best?

Would the same sealer for our head bolts work?

I use the ARP thread sealant on my rocker studs that protrude.
