Anyone use these? They are enternally oiled right? Meaning I gotta run a seperate line to the heads from the pan i guess?

If its like on my -1's it doesn't come from the pan it comes from the fitting at the back of the block where the oil pressure guage goes, its no big deal

As Jon said the external oil lines tap into the rear oil sending port. Be aware that the raised exhaust ports will not work with your headers. You'll be looking at a TTI stepped header for that application so factor that into the overall cost to upgrade the top end....another $800.00 usd.   ;) Unless you port the sr's they won't make any more power than the e-heads....both are comparable out of the box.   :P Also worth noting....you'll need to enlarge the pushrod holes with your new crane 1.6's or they'll rub. Have a close look at the adjusters...crane was having some issues with these in the past. Smith Brothers sells adjusters that work fine for this application.

I thought sr stood for stock replacement. Guess it should be NSSR for not so stock replacement.

could order the EZ heads with the stock oiling , this should reduce the amount of oil under the valve cover , which I prefer

Thats what im leaning towards but the price is right on these on ebay...


You get your ez's yet? How much was the shipping and how do they look?

we got 1 set here  they look good , there are a couple of things I am concerned about , I have not removed the valves to get a better look inside the ports yet but , they do not seem to have significant problems like core shift , very simialr to the Bulldogs in most respects , 76 cc Heart shaped chambers , 2.19 /1.81 valves, nice floor inthe exhaust ports  , the one thing I don`t like is they have restricted oil flow out of the heads & back to the pan needlessly with a wall under the pushrods & 4 very small holes to drain through where the Bulldogs were wide open like the factory heads , need to find out if the drain holes can be bored out or cut away so the oil can drain out of the heads  better

I got cnc'd SR's and love them. I just put some restrictors in the external oil lines to slow the flow, they put way to much oil up there...The Ez's don't flow as much on the exhaust side as the sr's do they?

Chryco Psycho

the exhaust port is lower on the EZ so flow is dropped some , but still a good head

The EZ's are an excellent head....i agree. The exhaust is a little weaker than on the SR but you can compensate for that with the cam profile.  ;)
