If there glowing your cam timimg is to far retarded, try advancing the timing Some original photos have not been recovered yet.

dw, the same thing happened when we ran our cam in for 20 minn.... it was toooo advanced and were glowing hot... except our extractors are custom made to avoid the lead issue.. get yourself some lead seperators, or is it that bad? gl

even a simple thingt like having the leads mixed up little will glow the pipes, it could be any of the above.

check cam timing, and how much fuel its getting
