to fix or OK to leave as is

[150aintenuff]

when port matching my new block I noticed 3 small cracks in the exhaust area along the bosses that the divider sets into, is it safe to leave them or do they NEED to be repaired.... they look like stres cracks from heat expansion as they line up with the most direct flame front out of the exhaust port...

remeber this is a budget build and if i can help it i dont want to weld on the block...

I haven't EVER cut the chest meat from a 260 block that DID'NT have the cracks where you described... LEAVE IT ALONE it will be fine !

Good luck,

i would at lease stop drill the cracks with a 1/8 hole ans then plug.
