soobme Posted February 13, 2004 Share Posted February 13, 2004 Out of all the stock EA81 heads, what are the best ones? As far as flow and valve size that is. Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted February 13, 2004 Share Posted February 13, 2004 Anything that was had an auto attached to it or after 85-86. These motors will all have hydrolic lifters and thus, bigger valves. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 14, 2004 Share Posted February 14, 2004 Beg to differ..... 84 Automatics have hydro lifters, and ALL EA81's made from 85 to 89 have them as well - auto or stick, doesn't matter. 83 and older will all be solid lifters.... ALSO - EA81T's had hydro lifters And yes - they have bigger valves, so these are desireable. GD (not sure if 83 auto's had hydro lifters.... maybe. I can't remember) Quote Link to comment Share on other sites More sharing options...
soobme Posted February 14, 2004 Author Share Posted February 14, 2004 Any one know how much bigger? Could U just have the older heads cut to take the bigger valves? Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted February 14, 2004 Share Posted February 14, 2004 I was in a hurry and didnt really feel like all that dribble. the turbo heads are a no brainer because THEY ALL HAD AUTOS! I guess I just neglected to mention the stick part. The valves would be a few mm's larger, I think. Don't hold me to that... Quote Link to comment Share on other sites More sharing options...
Russ Hill Posted February 15, 2004 Share Posted February 15, 2004 My daughters '83 2wd auto has hydraulic lifters too. Quote Link to comment Share on other sites More sharing options...
soobme Posted February 15, 2004 Author Share Posted February 15, 2004 Do U have to do any thing special to the engine to use hyd. lifter heads on a solid lifter engine? Quote Link to comment Share on other sites More sharing options...
