Hard blok filled b block question/ coolant hose to back of cylinder head.

[MOPARMAGA]

As some know who follow my thread, I did a tall fill on my block, the 1st side unfortunately was overfilled up to the bottom of the bolt bosses.
I drilled and tapped 3 holes on the side of the block and ran a small diameter masonry bit between the cylinders and one on the water pump housing area on the block to feed water.
There are the ends of the block that will probably not get coolant inside.

I was wondering if I should plumb another line to the back of the head in an effort to kinda keep those areas cooler?

Plan is -6an hose for coolant feed.

I'm just wondering if anyone messed up and how they fixed it without starting over with a new block.
Thank you.

Nevermind, I'm just going to do it.

I drilled and tapped a hole at the back of the block then drilled a intersecting hole into the port that feeds the back of the head. Then ran a external line to the back of block.

Seems like a good option, feed to the back (and sides where you tapped in), let it return to the front through the head up into the t-stat. Flush out the dust first so it doesn’t get into the system.

Thank you, I was thinking about drilling and tapping a couple more holes. If I can get coolant to flow around those parts of the bores that are blocked off I'd feel a lot better.

Thanks.
What I was thinking was just plugging those holes, and open up some of the head gasket slits so coolant can flow in and out freely.
Also trying to get some water moving around the areas that are trapped.
It's going to be interesting but I will definitely do some additional thinking on this.
