FORD_MAN 1,026 Posted September 14, 2018 Used to be a C1 C2 or D head, thats had the chamber machined to a open chamber. Seen a few on the forums/facebook, was done to fit later heads to earlier xflows so it wouldn't raise compression too high, XD/XE engine with a C2/D head would be close to 11:1 otherwise. 1 matt_lamb_160 reacted to this Share this post Link to post Share on other sites
77xcfalcon 177 Posted September 14, 2018 Thanks guys, i did a rough cc of the chamber and got about 45 cc. I might use this head on my xc block. Sent from my iPad using Tapatalk Share this post Link to post Share on other sites
matt_lamb_160 252 Posted September 16, 2018 Maybe measure again. Unless it has had a fair wack tacken off of the gasket surface, it will be more than 45cc. 1 77xcfalcon reacted to this Share this post Link to post Share on other sites
77xcfalcon 177 Posted September 18, 2018 I will get the machinist to do it properly before I get it skimmed.Sent from my iPad using Tapatalk Share this post Link to post Share on other sites
