Hello sir, I am fixing to recieve an 848 head that is going to be my "test bed" for just that very issue! I am currently looking at more modern approaches to an age old topic. These Stovebolts have untapped potential that just hasn't been realized by many in our generation. Most people are looking back to 1955, to try and revive these engines. When so much more advancement has been made in modern times concerning head porting and engine technology. I will be "sectioning" the 848 head for porting purposes, and putting together a photo journal step by step account of my findings to post and show others that might be contemplating mods just as you are. Hope this info will be helpful to you and others. Sometimes you just have to think outside the box. I also posted an intro in the "Bench Racing" forum giving some stats on myself titled "292 Speed Secrets". Hope to have some results to post soon.....Scott
