Fenderwell cutting templates !

I have those super comp hookers on my 65 Formula S . I must be doing something wrong when removing the engine from the car . these headers were a Pain in the A$$ removing them and installing them. Next time I remove the engine I'll try to leave the headers intact and slide the engine out without breaking down the header tube sections and removing them. What is your procedure on a early A ?

They will be put in and mostly assembled first, still not easy.
