Forte's is now in burlington, he moved from waltham a few years ago,
i have found its often too much trouble to buy local, no 1 has the stuff in stock, they have to order it, you still have to wait, then you have to pay sales tax, i would buy from summit, as long as you keep them new in the box you can return them if you never use them
If your set on gettin them local R+D speed in hampton NH may have them in stock, MPE in taunton is another place, but i dont think stocks them
or 1-800-230-3030
fwiw, i know a guy selling a complete motor with SQ blower/TFS heads/cobra intake etc complete and running 4500$ with 90 miles on it out of a 93
Good Luck
