What size breslin header bolts are the best for MAC mids on a 94
Z28 ??? Thanks

 

I went with the 1", figured the more thread gripping the better

 

Did you have problems getting them to fit past the primaries at all ?

 

Breslin? Just get regular header bolts. Mine haven't backed out at all on my MAC's. They are 1" standard header bolts. Just snug them up once every few days of driving for a couple of weeks.

I used the one's that came with my MAC's

anybody else ????

 

I ues the 1 inch stage 8 and no problems.

 

Retightening header bolts is a PITA and I dont' feel like doing that every couple of days. :P

 

1 1/4, hardened and heat treated bolts. Havent back out since i put them in months ago.
