OK. My 401 short block is in the shop getting bored,balanced...etc. It's a block assy i bought from a fellow i've never used.Just found out today it needs decked also.Always something unexpected! Now...i already have a set of INDY SR complete kit street aluminum heads for it. WHERE do i locate info/schematics...etc on adding the extra 3/8" head bolts to the lower edge of the 401 block?? Where in the @#$#$% do you get 3/8" head bolts and washers for the aluminum heads? I have the complete SR 401 INDY head kit...came with ARP head bolts and washers. INDY catalog states..."heads can be drilled for extra 3/8 head bolts". BUT...nothing about the 3/8 bolts are listed in the INDY parts book i have?? What ##, where do you get them? Can i use STUDS micxed with the ARP head bolts that came with the kit? ?? Also..HOW DEEP do you drill/tap the block? Need dimensions of the bolts,washers?? I have to take my heads in tomorrow so they can drill them out. ALSO..where do you get head gaskets with the extra holes?? Do you have to modify them yourself? I already have a set of ROL hi-perf head gaskets.Please email me direct with the info!! THANKYOU ,Joe __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
