Title: question on Stock heads and stainless steel valves Post by: RFbuilt on October 27, 2009, 19:34:48 pm was wondering.. on factory stock cylinder heads (bare , with guides and seats)
are the aftermarket stainless steel valves, interchangeable ? (intake stem thickness and exhaust stem thickness) asking because in my "how to rebuild" book.. it states for 61-74 heads stem diameter are as follows : intake - 0.3126" to 0.3130" exh - 0.3114" to 0.3118" not sure if the diff of 7.94-95mm intakes and 7.91-92mm exhaust stem dia. would be big enough? to not be able to interchange exhaust stainless valves into intake or vice versa.. thank you guys |
