Re: 3988336 small bl heads
The book I have, Cars & Parts Catalog of Chevy V-8 Casting Numbers is showing the 3986339 as a 69-73 307 C.I.D. Truck head with send(?) hole and with accessory holes in both ends of the head.
Obviously Truck only, so that may be why it doesn't show up in the Guide. Lew

Re: 3988336 small bl heads
339's are in the guide as 71-72 307's. What are your casting dates on your 336's
