[QUOTE=jerry clayton;

The head bolt cracks was common point and can be prevented somewhat by putting the tapered plugs in the water holes to support the deck and then drilling to size necessary[/QUOTE]

yep i did a sbc and seen bbc as well . i tap the big upper water/ steam holes in the deck and then used a soild iron pipe plug there hard to find now with out the dip in the threaded inside of the plug. then i tap out some round stock to hold the pipe plugs and drill for steam hole s faced the square drive and shoulder off the top in the lath .so there was less to deck off .i know that they sell a hex pipe plug but like the job better with the iron plugs more iron in the deck when done .yep dave i went around and around with a guy i built a sbc blower engine all the work and a block that may not hold the boost load of a 871 should of use a shp dart block .but he did not want to spend the money .oh well when all said and done with his old block the shp block was only a bit more
