hey guys this is my first thread ever so bare with me. i have a 73 k20 th350 with 4.10 gearing. going to be running 900r16 ( 36 inch military tires). The engine in it when i bought it was a totally gutless. it was supposed to be the original 350. turned out to be a 88-94 305 with an old set of gen 1 heads on it. so i picked up a 350 4 bolt out of a 72 camper special. so i was wondering about putting the 305 heads on to boost compression. they are the 416 casting. the cam kit that was in the 305 has new springs in the heads with new push rods and lifters. the cam is comp cam 12-206-2. wondering how this combo would work for me. the truck is used as a daily driver in the winter and a tow rig and some off roading in the summer. thanks for any help
