FE Technical Forum / 428 c1 heads
« on: May 17, 2019, 09:46:42 PM »
 I have 2 sets of c1 heads for my 428. one pair is cut .050 and one is .010. the valves on the cut pair are in the seats by .050 more too- will that be a preference disadvantage? which would you choose?  thanks
 does multiple valve jobs where the valve is recessed hurt hp- if the valve is recessed .050 from valve jobs that obviously isn't equal to .050 less camshaft lift- correct?

FE Technical Forum / pump gas compression
« on: February 03, 2019, 09:20:16 PM »
 I have a .020 over 428 with what is apparently 28cc dished kb pistons and 70cc iron heads already cut .010. What can I do to get the compression correct for 91 pump gas.  It also has a cj cam. Thanks
