Do you know why it blew? Do a leakdown before disassemblY?

Now if I were to go with Toomey t5 and pods would the jetting point still be around the same 27.5 and 300-320?

Be sure to leakdown test your new motor, an air leak could have caused previous failure.

 

Always check jetting after any change of how air flows in, thru, or out of engine, with plug chop/plug read.

Start rich and work down.
