Full Floater Posted Monday at 04:56 AM Share Posted Monday 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?

mowerman Posted Monday at 03:20 PM Share Posted Monday at 03:20 PM Hell I’ve had 2 of them apart years ago I don’t remember but I would guess thier both the same part number… good luck 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76218-e6-2v-head-interchangeability/#findComment-586789 Share on other sites More sharing options...
Full Floater Posted Monday at 09:16 PM Author Share Posted Monday at 09:16 PM 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 yesterday at 01:26 AM Share Posted yesterday at 01:26 AM 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 20 hours ago Author Share Posted 20 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 20 hours ago by Full Floater 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76218-e6-2v-head-interchangeability/#findComment-586848 Share on other sites More sharing options...

Popular Post Joey Mack Posted 18 hours ago Popular Post Share Posted 18 hours 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 4 Quote Link to comment https://www.bigmacktrucks.com/topic/76218-e6-2v-head-interchangeability/#findComment-586852 Share on other sites More sharing options...
Freightrain Posted 15 hours ago Share Posted 15 hours ago Is the seat smaller than the angle? Maybe that would be correct and is actually at the match line? I'm working on pulling my 300 heads apart and checking things out. 1 Quote Larry 1959 B61 Liv'n Large......................

Vladislav Posted 10 hours ago Share Posted 10 hours ago The heads are interchengeable. The only point you have is a small tube between two heads connecting them (fuel drain?) and there's a plug with Allen head at the corresponding end of each head. So you might be needing to change the tube fitting with the plug if the particular head was mounted in the different position on engine previousely. No info on the peened seats from my side. Looks like a rocket technology of someone who provided a seat swap in a shop with hope to secure them better. Wouldn't make any help as it seems to me. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/76218-e6-2v-head-interchangeability/#findComment-586873 Share on other sites More sharing options...
