Sorry, slight thread hijack, but an order of magnitude more important than the heat transfer of pushrod tube paint vs plating is the head casting itself.
Just been into cleaning up my newly acquired 2L 3 bolt intake heads (039-101-371A) and I noticed that casting flash had substantially blocked off many of the thru cooling passages between the fins. Lots of cleaning up with long drill needed to get flow passages opened up to intended areas. Photo shows area of concern. I did more clean-up after this, but you get the idea.  Note that my older 2L buss heads 022-101-372G were much better for flash. So while you're in there folks look closely in those passages. |
