I'll admit, that's about the only way I can afford it.....BUT I draw the line at not having certain things dead on. Like crank clearances, guide clearances and seat and valve faces, for example. I don't compromise "there".
Crank clearances were checked by the machine shop.
Aluminum Edlebrock RPM Heads were checked out and assembled by Indy cylinder heads. I got them for a song new though via the Mopar Tim express
