On the le1 package, do I have to send my head castings first, or can I do it toward the end of his services? Also can I use crane SA 1.6rr w/ Lt4 Valve springs on this package?

 

The package comes with springs. I believe he likes to have your cores to work on first. Get with Lloyd on this though. He may have a way of working around this. SA rocker arms are ok to use but many people dont like them.

 

Yes you have to send him your castings or he can use an extra set he has but you would have to pay a core charge. The Crane SA Rockers should work, I run Comp Pro Mags on mine.
