Some guys are saying 30 degree seat ,others are saying 45 on these heads,if we are talking about the early cast iron head
If you use a 45 deg seat can you put a 30 degree top cut in ?
If you use a 30 deg seat cut and no top cut like Gary is saying then I assume a 45 seat with a 30 tc is feasible but if you sink the valve it might be difficult to shape the SSR to the seat or (bottom cuts)if any.
Again I am just trying to visualise the valve job,I found only 1 picture of a early V8 pontiac head.
I am not saying one is better than the other just wondering how people would do a valve job on that type head.
GARY - I do have some 23 deg sbc heads with 50deg seat and they run
