Hey guys . I poured a can of seafoam in the tank and then followed seafoam directions for cleaning out the intake and letting it hot soak. When I restarted it I reved it up to about 3500-3800rpm and blew the block heater out 
i bought that from lmc and i knew it was slightly larger than I needed , but it sealed up fine with the exception that there was 1/16” gap on the top between block an plug rim . I’ve driven it with no problem for a few months . I think it’s this 0° weather that’s mabey made my block contract more than it ever had since the plugs been in . So my question is how hard is it to get a normal steel freeze plug from Napa pounded in there ??or if it’s a better idea to stick one of the rubber ones in ??or have a shop do it ?also will an average shop be able to install one ?

Well, you haven't blown a power valve as Edelberries don't have 'em.

If you have to replace a "freeze plug", get a brass one. They last longer because they don't rust. You can use a bearing driver, or a socket (of the correct size) to drive the plug in. You shouldn't need to take it to a shop for just that.

They should, but I like to know my business when I go to the box stores.

I installed an exspansion plug yesterday . Thankfully It started right up . I didint know what it would do with all the seafoam in he engine . I took it for a drive and it ran great . It seemed better than before and it was 150-200 rpms below what it usually is at 60mph . Idk if that’s from the seafoam or because I treated it to some high octane . I was going to get your guys opinion on spraying another can of seafoam in it . This morning I had a lot of trouble getting going on the highway . It was bogging down and bouncing around a little till I got past 45mph then it smoothed out and ran great . Kinda like once the rpms were up it cleaned it out better , but then after driving through town for a while and then getting back on highway it did same thing till I got my speed and rpms up. Does it mabey still have some varnish in there that gets blown out when rpms are up and then settled back down when they aren’t ? The seafoam wasn’t as big a success as I was hoping for since I blew freeze plug just as I was getting to the point when lots of smoke started coming out ,so it might of not really cleaned it out much

My suggestion would be to yank the carb and clean out the fuel circuits. The old fuel could have "gellified" to some degree in there. Could explain the lousy running at low RPMs and better running at higher RPMs - the amount of fuel passing through the carb's mains and all.
