Just checking before I start the switch.
Looking at them and doing rough measurements it seems that the
stock bolts will be OK with thin washers. Is that right??
I had the heads since the 60's so decided to up the compression
on a stock 8BA with Fenton duals.
Thanks

Bolts should have at least 7 threads in-gauged. However there are 3 blind holes per side and these usually won't take more then 9. Usr harden washers on alm heads and torque to 45 ft/lbs for 3 heat cycles.

I always used the stock head bolts with OFFY heads and they worked fine.
