Default A few questions about items needed for CNCd heads install

Sometime this spring I would like to install the TFS 215 heads I got. I know I will need head gaskets, head bolts, some Yella Terras, bigger injectors, & maybe rocker arm bolts. I was talking to a local guy & he said 33lb injectors would work. Also, do Yella Terras come with mounting bolts or can I use the stock ones? I found some Edelbrock rocker bolts made shorter for CNCd heads that dont protrude into the intake ports, should I get them? Also I was told I can use the stock valve covers but I will need to cut out the metal shields so the rockers clear. I just wanna figure out exactly what I will need so I can start getting this stuff lined up.

Edelbrock rocker arm bolts are for intake only so they say. Only comes eight to a set. I found GM rocker bolts P/N 12560961 at Scogindickey for $4.55 ea.
Wish they made taller valve covers, I didn't know they would have to be modified to clear Yella Terras/

Thanks for the info. So do you think 33lb injectors will be enough or is that borderline?
