A good valve job and set the throats at 90%? Any suggestions on valve job angles? From searching airflowdevelop wrote 39/45/60/75/90 the thread was about 243 heads so I'm wondering if this applies here. I'm guessing that kind of valve job will take care of the throat diameter. I figure that a 2.00 valve would be wise, while leaving the stock exhaust valve size.
To give an idea on application:
233/241 at .050 111+3 (rough estimate from cam grinder, yet to purchase)
PAC 1218 springs
Long tube headers, speced by pipe max 1 5/8-1 3/4 3 in collector
Pg trans brake
4800 stall 8 inch
32 x 14 tire
3061 w/ driver.
