I know this is a LITTLE off subject, but you guys sound like you know what you are talking about.....
I've got a set of Bowtie heads I want to put on a 400. My machine very trusted machine shop said i didnt have to drill steam holes.....EVERY where else i look, says you must. Any Thoughts on this. This is going in my circle track car, so keeping it cool is a must!
Thanks for your help....
