i pancaked my nice running motor, and cracked an upper engine case on the left side really un-weldably bad. i bought a really nice looking f4 motor, thinking it was for an f4i, but i ran the number and its not. the dude is willing to give the $$ back, but i still need a motor. i am pretty gangsta at swapping parts and have a service manual. So, my MAIN question is.... can i swap out just the head and the old f4i lower end will work fine, cause the only differences i saw was the sensor missin on the left side of the head( a dead giveaway i had an f4 motor) and it had vacuum lines coming from the back of each cylinder....i have an important show on the 22nd, and need this bitch rolling!!! please HELP
