morgey Posted January 7, 2017 Share Posted January 7, 2017 Anyone know if these are removable and if so are they just push fit. Im asking as im going to be skimming a 4efe head and these are going to make it a pain Quote Link to post Share on other sites
Ep82gi Posted January 7, 2017 Share Posted January 7, 2017 You don't need to remove them to skim the head but yes you can remove them the same way you can remove valve seats from the 4e heads. I use an old BBQ and cook it for a few hours. Same with re fitting them. But I wouldn't suggest sticking it on the BBQ after skimming it.

morgey Posted January 7, 2017 Author Share Posted January 7, 2017 The problem i have with leaving them in is i have to stick it on parallels on the rocker face leaving the block face at an angle. The problem here is i dont have a fly cutter big enough to stick the head on the mill over and do it in one cut. So if i can remove them i can clamp it on an angle plate much easier and clock the head flat and buzz over it that way. I can also use the cnc then which is much more accurate.Ideally i would use a surfsce grinder but we dont have any wheels suitable for ally.Cheers for the tip though, i have large ovens at work so could always bake it in of them for a while before and after.

Starlet__SR Posted January 8, 2017 Share Posted January 8, 2017 (edited) Might be worth chucking it in the oven and dropping them out. For refitting, just chuck them in the freezer or some liquid nitrogen. Edited January 8, 2017 by Starlet__SR Quote Link to post Share on other sites
