I could use a little help/ information. I have a 1946 Chevy pickup with a 216. Parts are hard to come by and very expensive. Got a buy on six brand new .030 piston for my 216. Got them from my ups lady open the box and to my surprise they are slightly domed not the flat top I was thinking I was getting . They are for a 216 and marked for 1937 to 1953 216 . What is it with these pistons and will they work in my stock 216. Why are they domed. Help and information greatly appreciated and needed. Thank you .
