Re: 186 Head ???
Hi Bob, going to pass at this time on heads, (this time around), wrong dates. I believe you had another post up here about using those 186's on a 400" SB. Save your money, they won't deliver, been there, done that. Thanks, Gary in N.Y.
P.S. The heads in the trade deal are the SB "Australian's" that flow 260 CFM from the box and will make 440 HP (easy-no porting) on a 383" stroker, they are excellent "budget" heads for between $500.00/$600.00 (pair), and perform equally well on a 400" SB. One more item, the heads in the photo's (with the chamfers all chipped away) are totally repairable back to new AND original looking with NO welding. We do many on those repairs we see from resto the shop on the early SB's. Even cracks don't matter as long as they're shallow and not down to the bottom of the head. It's a very expensive repair however!
