Default TFS 235 head fit and clearance questions

I'm getting a 427 built by Erik at HKE and its going to have TFS 235 heads. Two questions, 1) will my stock LS1 valve covers fit, and 2) will those stock valve covers provide enough clearance for 1.7 Yella Terra rockers?

I'm assuming the answer to both is yes, but just checking to avoid last minute delays... thanks in advance.

I'm having a 427 LS7 with TFS 235's being built by Erik at HKE as well. Your stock center bolt valve covers will be fine with the Yella Terra Ultra Lights.

Thanks for the info. Sounds like we have a similar build. What size cam are you going with and what intake and fuel injectors if you don't mind my asking? I was planning on the FAST 92 set up, but haven't decided on injectors yet.

FAST 92/92 portmatched by Greg Good With Delphi 42# injectors. The cam will be hyd in the 25x/26x .650 range.

How far along are you with your build? Mine should be ready very soon.

I just ordered mine 2 weeks ago so I'm well behind you. My cam specs will be similar. Are you doing an L92, N/A only build? Thats what I'm getting...

I'll be keeping my eyes open looking for your results!

Thanks, glad I don't have to add new valve covers to my list.

Cool video by the way.
