228/234 .588/.598 112 LSA XE-R cam
Either 7.400 for light preload or 7.425s for a bit more. (both will work, 7.425s will be a bit quieter)

I was identifying the cam and suggesting to you pushrod sizes if yours is a cam only (stock heads, stock gaskets)

Generally they'll send you some 7.400s, but the base circle is smaller than stock, so, to keep the pre-load close to the same, I always recommend the 7.425 like Pred mentioned.

On my car, I milled the heads .024, used a thinner gasket, and 7.400s. IMO, it achieved the proper pre-load. On my previous car, with just a cam, and the 7.400s, the valve train was noticeably louder.
