Richard and It1s10 Thanks for the advice. I called comp cams and asked if I would need a converter for this cam and I was told no. I mentioned what you said Richard about the cam being a little more agressive in a 305 than a 350 but he felt that the engine wouldn't stall in the 1800 to 2400 range. I seem to have more confidence in your answer richard and if indeed it does stall I will put it on since it's not a major undertaking.

Don't know why I keep sticking with the 305 but it's been good to me and with the new heads and cam I should pick up substantial HP and torque.
