Hello fellas. Piecing my motor build together and looking into the Holley valve covers. I’m just wondering if anybody is running the tall Holley valve covers? I searched and I didn’t get much info. Seems like one person had them with no issue with alternator, which is the main problem. Running yella terra 1.7 rockers so I’m either gonna run the regular Holley valve covers with maybe the spacer yella terra offers or just the tall covers by themselves. Anybody using the tall ones ?

WOW. No one has these covers?

I put on the Yella Terra 1.8 this fall. I too didn;t have enough clearance.
I didn;t want to use aftermarket covers , and the spacers end are expensive and
potentially give two places to leak..
I don't remember the part number , but BTR sells the "thicker" gaskets made
by Yella Terra.. They worked perfectly for me

I have the thicker gasket made for the yella terras. I havent had them installed yet but will in a couple weeks. Bought them from Mamo.

YEah I saw that thread. Not sure if I wanna take the plunge on the tall covers without being certain. One positive experience doesn’t inspire me to purchase them. I might just run the stock size holley covers and run the yella terra gasket BTR sells.

be certain about what?... it was pretty clear that they do fit except for the coils which you can either use one bolt to hold yours down or get the newer style coils

Yea your right. I already have newer ls3 coils. So I’m gonna pull the trigger on these. Thanks fellas. I appreciate it

I'm running them with Yella Terra rockers and zero issues. LS2 coils.
