Frame numbers and Factory head mods questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I have an original 72 LWB that I am going to transfer to a 68 Short chassis I bought. What are your opinions on "cutting out' and welding in the original matching frame numbers from the 72 to the 68 if I scrap the 72 frame afterwards. Or should I just grind out the numbers on the 68 frame since not all frames came with numbers?

Secondly, the 72 is an original 402 BB are there any Head modifications I can do without swapping pistons to increase the HP since in 72 the 402 is only rated at 240hp? Thanks for any suggestions.
