hello, picked up a pair of "452" b/b heads for my stocker, has a 1/8" pipe plug on one end. is this factory? motor home?? never seen this before. also appear to be surfaced quite a bit, casting numbers on deck surface top 1/16th have been machined. deck thickness on lower head bolts is 1.00 thick, what's unsurfaced thickness?
all parts are sold as is, all parts are considered used no warranties or returns paypal/check/money order, shipping is from zip 02891, buyer pays paypal fees 24% IRS 1099A plus 3% of part price, check/money order preferred site is not monitored 24/7 there might be a delay in response

What kind of spark plugs do those heads use? I’ve heard that uncut heads measure a little over 1”, but I’ve never measured personally

906's usually measure 1.00ish from the factory ,I never measured the set I had gotten from Paul Rossi back in the 80's , they were NOS castings , small plug with the water ports around the spark plugs.
What's the depth of the open part of the chamber , the set I had were over .100 , as deep as .130 in the center of the head.
running up my post count some more .

The 1/8" pipe plug is factory and I believe to be only on motorhome heads. I just sold a set like that a few weeks ago.
