Just another small update on the out-of-the-box Speedmaster heads...
And please remember when I say out of the box I still paid $95 to a machine shop to have them take them apart inspect them pressure check them re lubricate and put them together and they're only complaint was the heads sat a long time in the lubricant that was put on there had dried up.. They didn't think it would have caused problems, but they also didn't think it was a good thing..
Anyways put a good 40 miles the other day on the freeway and a little bit of spirited driving here and there... Knock on wood so far so good...
I do have one video I'd like to pass on to @lead69 and his fancy trick flows..
