[Bubby Sharp in KY]

Head Problem ?? Just back off the studs like Don told you . I have installed three 5.5 and one 6.1 , No problems except one had the wrong gasket with it . Must use a B gasket . I installed a stock 28 head with the FORD script and had to back off some on the studs. Be careful cutting down the bosses as they might be a little thin on the water jacket at that point . What are the problems with the 6.1 head? Bubby Sharp in KY
