Buy the
rba head for 12 bucks. I put a .8 28 gauge build on one and closed the airflow off some and the flavour was crazy. I did a .3 with 24 gauge on another leaving the AFC wide open and it chucks better then my TOBH with the same build. It sounds false but I tell you no lie, it chucks something crazy and the flavour aint bad either but I prefer the .8 build. I dont know about rebuilding the actual LVC heads, sorry.
