With my knowledge of moving around on a pc, it would take me longer to get the proper way than to actually drill out the holes. What are your thoughts........thanks. Oh and yes I picked up a 180 stat although they were sold out of the regular so I ended up going with the fail safe since I couldn't justify added price of gas and time to go to another store.
1. If the sealing surfaces are smooth and even, you don't need any additional sealant on either side of the gasket. If the thermostat housing or the goosemeck is pitted, it won't hurt to run a thin fingerfull of rtv silicone over to fill any pits or scratches in the surface before you install the gasket.
2. Two 1/8 holes might actually affect the cooling, causing a noticeable increase in the time required for the thermostat to reach its opening temperature. I think the most important reason to run a drilled 'stat is to provide an air bleed to facilitate the movement of air out of the lower intake manifold. I make sure that the hole or one of the holes is at the 12:00 O'Clock position for that reason. In the winter-time you might want smaller or fewer holes, as the engine will take longer to warm up with bigger or more holes. I think I drilled two 1/16 holes in mine.
