This is the first Honda I've ever rebuilt I was just wondering if the head bolts, main bolts, ect. need replaced during a rebuild. I know some engines require this due to stretching bolts. Thanks and check out the new pics http://www.geocities.com/crxbart/my_car

 

If you plan to use this engine for performance, more than daily driving, replace all of the head and main bolts! You can get away without replacing them if it were to just be a daily driver n/a, but it's a small price to pay now to know that everything is fresh and tight. And yes, the bolts do stretch on honda's.

 

i would replace the headbolts with new oem pieces. you can reuse them if you have to. you dont need to replace the mains tho.

 

Yes, you do need to replace the head bolts... ARP's highly recommended, order the GSR kit and use a couple washers on eash stud. You don't need to replace the mains... i've NEVER heard of needing to replace the mains. Local shop's 640hp motors are on OG mains.
