Ok, i just got my 165 AFR's in, trying to figure out what is the best route w/ the head bolts. The AFR's are 1/2" drilled. My 289 has 7/16 bolts. I found a set up ARP 7/16 bolts and some APR step washers for about $80 total. Or would it be better to get these bolts that have the widened head area. Not sure what to do..

I went with the ARP bolts that have the wider head area. Seemed to me it was a better option than the step washers. I put the Windsor Jr. heads on my 289, not at all a strip car but it has been 2 years since the head work and no problems yet.

those will not work, use the inserts
Woody, can you explain the problem w/ those bolts. I don't have a problem using the inserts , it just seemed like it might work better them..

I used the 7/16 with stepped washers on my 289 w/ Windsor Jr. heads, no problems after driving it fairly regularly for 3yrs.

I like ARP 7/16" undercut studs with the step washers.
