On a mild street engine with factory head castings, I focus on the bowl area, doing very little on the guide, and some work in the ports. No chance of guide movement, no chance of breaking through, durable as can be.... and always excellent results.
Hey,
thanks for the reply. Your vids and posts are one of the reasons I thought Id give this a go. :) Ive studied them quite a few times and I should have just stopped there, but Id have always have thought how much further could I have gone. :D Its awesome I have your vids on my thread, its easy access for me. :D
I have a set of J Heads in London I can have shipped up and I have another set of J Heads that came of my '73 340 but with over 50 hours in on my first 596 head I dont wanna throw it away just because I bust through my second one. Although I have a much better handle on what Im doing I could easily half that time.
