Thanks for all the good info.
I have another question that I hope does not show my ignorance. In regards to a previous response:
" Don't waste your time messing with the pushrod pinch "
What is the pushrod pinch?
Also, thats a great idea about building a box attached to a shop vac to safely carry all the metal shavings away.
I will ask some of the junkyards in the area to see if they have any cracked #882 heads that I can have so I can cut them in half.
