Thanks guys!!
Just trying to figure out if I could put them on the 350 I am trying to piece together. Guess at best I'd have to get larger valves put in to make it worth while? Gee... So many problems in trying to save a few $$$....
five7kid... You have answered alot of questions for me about this motor, and I really appreciate it!! Told me the heads on that motor were bad, that is why I was looking for an alternative solution. Any thoughts on getting the 305 heads done? (Anyone feel free to answer this... THANKS!!!!!)
