for all intensive purposes we all get aggrevated when we reach a performance level and hit the wall for lack of available parts.the new trick flow heads appear to have great quality and potential for those who use them.all the better.its very hard to understand why the mopar block situation has reached this level at all considering that block castings have been around since horses were delivering milk and nobody except kb can get it right in 2014.i dont think anybody here was or is bashing new parts,just the lack of higher level performance parts.i for one hope that these new parts are like chinese resturaunts,when one pops up,in 30 days there will be 75 more.the ultimate goal for everyone is to go faster....
