I know, I know, please not another Speedmaster post.
Ok guys second head vacuum checked great, guides great, chambers look very nice but will really get checked over on my porting bench at a later date. So far I’m going to say I’ve touched at least 15 sets of these heads. The only bad set was a bare set of a customer and I ate a couple hundred dollars fixing them. Bad unfinished chambers and one valve guide .003 over sized. Lesson learned for me because Speedmaster did nothing about it after a couple calls and several emails. I bought two sets but I bought them loaded. My thinking is the are hand assembled and probably go through a better quality control. For a little over 700.00 loaded I think it’s a smart move. I told you what I would do but I have the tools sitting here. Speedmaster is here to stay and are hitting all the big performance shows across the United States. Over the 3-4 years that I’ve been buying them I’ve noticed small changes for the better. Sorry the pictures aren’t better but I’m not setting these on my grubby porting table right now.
