Thank You Gentlemen;
I was pretty sure there was no issue with a blocked port in the head when there is no corresponding hole in the block. My first concern was that the head was wrong but when compared with the original head all holes line up.
I will double check to see if there are any head bolt holes in the block that penetrate the water jacket, thanks for that heads up.
Now that the head issue is over I can move forward on the build….once the cash comes back :-)

Have a great weekend!
