After talking to Aaron again & I'm trying to make this head issue a little mow clear.Ok the 5hp & the 28 Flat head is legal now in Pro-X & Super Mod Single.It is a billet Alu. head that can be run with one or two plugs,I relocated the original plug from the stock position & added one mow.Ok now that thats out of the way the OHV head looks allmost identical to the ones yall are running now with the exeption of some changes in the week spots that Briggs left us with.As of now it will be a cast head just like the Briggs head.Hope this helps explaine it a little better.Please go here & vote.
