Full Floater Posted yesterday at 04:56 AM Share Posted yesterday at 04:56 AM Needing to do a quick and dirty front head swap on a 237 for someone here quick. It has a loose valve seat on cyl 3. I have a couple parts engines. Are the front and rear heads interchangeable? Just curious so I can use whatever appears best after pulling them. No time for sending it away for any machine work. I guess there's nothing much that can be done with the existing seats in the donor head to help prevent them dropping, is there?

Full Floater Posted 15 hours ago Author Share Posted 15 hours ago I keep getting an error code 200 when trying to upload a pic today, but on my parts head that is going on, the exhaust valve seats have some peening around them. Was this factory? I haven't noticed before, but also never paid much attention. Haven't pulled the bad head yet to look at that one. I know this parts head has been off before years ago for an inframe, so maybe something was done to the seats or someone peened them to prevent them from falling out. I will continue to try to upload the pic until it lets me 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76218-e6-2v-head-interchangeability/#findComment-586820 Share on other sites More sharing options...

terry Posted 11 hours ago Share Posted 11 hours ago I have seen the head area around the exhaust seats dimpled with a sharp punch before. terry Quote Link to comment https://www.bigmacktrucks.com/topic/76218-e6-2v-head-interchangeability/#findComment-586841 Share on other sites More sharing options...

Full Floater Posted 3 hours ago Author Share Posted 3 hours ago (edited) Any tips to placing the fire ring in the new head gasket? Been a while, can't for the life of me remember using any sealant to hold the fire ring in place or anything. Thought I'd better ask. Here is a pic if the peened seats on the donor head Edited 3 hours ago by Full Floater Quote Link to comment https://www.bigmacktrucks.com/topic/76218-e6-2v-head-interchangeability/#findComment-586848 Share on other sites More sharing options...

Joey Mack Posted 1 hour ago Share Posted 1 hour ago as far as the fire ring goes, I was taught to place the sharp edge down. The ring should fit nicely around the top of the liner Quote Link to comment https://www.bigmacktrucks.com/topic/76218-e6-2v-head-interchangeability/#findComment-586852 Share on other sites More sharing options...
