Engine Valve Cover Clearance With Crane Cobra 1.72 Rr's

should be fine. I have ford racing 1.6 rockers with a tfs1 cam under oem chromed valve covers with the baffle removed and felpro blue rubber gaskets and no clearance problem. worse case is uf you do get some interference on mock up get the felpro double thick cork valve cover gaskets.

I am facing a similar issue. I have 1.6 rockers that originally hit the cover with a comp xe274 cam. It was grinded out to clear. However since then I had to do head gaskets. Now I would like to rassemble the motor with 1.6 on intake and 1.7 on exauset for better air scavenging and I'm running stock valve covers over AFR 185 cc heads. The intake is a trick flow with no spacer. I ordered a 3/8 phelonic spacer but haven't got the heads back from machine shop yet. I hope the 1.7s clear like my 1.6 do. I don't want to buy tall valve covers beacsue they supposedly will not clear the upper plenum on the driver's side valve cover. Any advice? Will the 3/8 intake spacer solve that if I get tall covers?
