It's too big they say....Mast has a different view!  When paired with a large displacement engine our LS1 295 heads are a force to be reckoned with.  Designed for all-out performance and power this head really is a beast flowing 412 cfm!!!  We have customers running their best times after ditching the competitions 245cc heads and stepping up to these BIG boys.  In fact, one customer reported that he gained 7 tenths in the 1/8th mile by switching to the Mast 295 heads from a 245 on his 427, making NO other changes!  Now that is a serious upgrade.
