Need to fix a couple stripped threads for the intake before I put it all back together. These are the threads in the heads that the intake bolts go in. Does anyone know the exact helicoil size that they take? I can take a bolt with me but I've learned not to listen to the guys behind the counter so much. Basically, what size are the intake bolts and that'll probably tell me what I need to know.

thanks

 

3/8-16 is the normal bolt size and thread.

 

thx shoebox..
