Hello all, on my 64 k ram, I plan to block the heat tubes for the rams at the header. i did this before and found no problems. Although for a little while though, then i ported the heads and made them functional again, just because. i know cold intake charge and gas is very beneficial, so it makes sense that not having 400 degree ( or something ) hot air run under the base where the air flows would be good. I live in california, so cold isnt a problem, i know it doesnt serve a functional effect to the ram theory and air flow, so anything im not seeing, that would stop someone from doing this? The looks remain physically identical as a freeze plug goes in the holes on the headers, so thats not a reason either. Sory about the spelling and puncuation. thanks all, tim ps, my car is coming along nice at the body shop, lots of hidden stuff under the paint, but nothing they cant take care of. thank you [Non-text portions of this message have been removed]
