[QUOTE="SFO, post: 696290, member: 21864"] If you want to put a real cam in it you will need shortened guides and a spring kit, so while it is apart I would suggest the KMPI stuff. They make SS valves for this motor too. Blend the seats, have your valve job guy open up the throats and unshroud the seats on the chamber side, I think the short turn is pretty good on this intake if I remember right. If you end up putting a big cam in it make sure the valve job guy has it, (the cam) so he can check the valve to valve clearance, things get close in these rfvc heads pretty quick. [/QUOTE]
