[DeTomaso] Removal of pipe plugs when 351C heads are hot-tankcleaned?

[Charles Engles]

Dear Doug,


               I have no experience in having this done, but if it can be 
done by the machine shop, then I would think it would more thoroughly clean 
the head coolant passages and could provide a small incremental improvement 
in coolant flow and lowered temps......., but I dunno.

                             IMHO,  Chuck Engine Rookie Engles
