Chrisred Posted April 18, 2017 Report Share Posted April 18, 2017 Where can I find a nice head for my 520? Any tips on changing the 520 head gasket? This will be my first time cracking this motor open and only 2 time doing a head gasket. My life feels so empty without my truck :( Quote Link to comment
datzenmike Posted April 18, 2017 Report Share Posted April 18, 2017 Any '65-'69 L520 and L521 have the J13 engine. Best to just send yours out to be rebuilt. Specify hardened valve seats, new guides and valves and seals. A light shave off the bottom to true it up and you have a new head. If wooking the by one try a want ad in our classifieds... http://community.ratsun.net/classifieds/category/4-engine/?sort_key=date_added&sort_order=desc ...

zed1 Posted April 19, 2017 Report Share Posted April 19, 2017 Take your head to a rebuilder. A used head you buy may be in worse shape than the one on your truck. Once the engine shop tells you what you need, springs, seats, valves, rocker arms, etc. this form can help you locate the parts.
