Ok gang i am asking two questions here...1.) Will the 2003 vortec heads work on the sy/ty engine.......and what changes have been made to thses newer style head. and 2.) When modifying ...is it easier to modify the vortec heads to fit to the lower intake or modify the intake to fit to the vortec heads. Also is there a web page/site that shows detailed pic and instructions of how to do the modifying to fit heads to vortecs to intake and vice versa...
thanks ,

You have to modify the lower intake, which ever route you choose. If you are using spacers (not recommended by most) you have to machine down the distributor boss. If you are not using spacers, you have to weld up the lower intake, so you can port them to meet with the taller ports on the Vortecs. I went this way. You can buy an intake (providing a core) from E (turbotime.us). If you have the modified intake you just have to drill up the Vortecs for the old bolt pattern, we are using and JB weld the bolt holes. I did this myself, it went easy...

HTH,
