well i have a pr3-3 which from what i know is a b16 head. now i have a ls/vtec turbo build and i'm wondering how bad this nick in the head surface is. is this deep or not that bad. basically with my bottom end i'm sitting at 9.8:1 with a stock b16 head. my only worry is that after resurfacing to get rid of the nick its gonna bump the compression too high to be able to run on my build. any insight would be great

 

id try using some permatex indianhead sealer. id def. try that before i scrapped the head. just coat the gasket with copper spray as well to be safe

 

ok well for the boost levels and compression levels it will be reaching i'm not to comfortable in patching anything. basically I will be either resurfacing the head (if it wont raise the compression too high) or sell it to someone going na and get another head

anyone else???

 

that nick doesn't look like its in a critical area. A resurface is a must regardless if you like it or not...but if you had a nick going from a cooling passage to the combustion chamber then you run into issues with sealing

 

yes it will be resurfaced if i'm going to use the head. i'm looking to run a maximum of 9.5:1 and pushing 9.8:1

any thoughts on getting it welded? like get a welding shop to fill the nick (i would imagine tig welding it) and get it resurfaced?

end result is i want the nick gone 100% and not to bump my compression up in the process

 

Sure you can get it welded but why when its not a serious issue. there is plenty of material around the area to seal the hg. also there is no way of getting away from increasing the compression....just because its gonna be resurfaced. if you are so concerned just get a thicker hg.

ok well if you look you can see the blue silicon i used to check where on the head gasket it is open or not sealing. it's directly in the middle of the water jacket ridge. so basically i will have coolant flowing around the head stud. from what i know its not suppost to do that. i will be running a 3 layer factory honda head gasket, so as thick as they come. it's something i will get filled and resurfaced then. i'm not gonna mess around and half *** this build

 

i would have to say just get it welded, and then machined, and you wont have to worry about it. That would be the right way to go.

 

i would just make sure no material petrudes and surface is flat and leave as is. that area is not critical to coolant nor combustion sealing
