[Fot] TR4 Valve spring - pressure, assembled height, suppliers

Greg,

I am doing a valve & guide job on my TR-4 head. My cam is a Babe Erson
BFE-149 with intake of 430 and duration of 282. My normal shift point is
5000 rpms with a never exceed of 5500. Inasmuch as I drive my car to events,
reliability, not brute power, is the game plan. 

May I ask your recommendations on valve guides (bronze vs. iron), their
clearances and spring pressures? What about multi-angle valve grinds?

Another issue. I found a conspicuous crack between the center 2 water
galleys between #2 & #3 pistons. It looks as if it's been there forever and
does no harm. Does that render my cylinder head toast?

Thanks,

Richard  Taylor
TR-4 #196
