Vortec L 30 heads, Machining?
I've got a great deal on a set of Vortec heads, not the L31's for a 350, but the L30's for a 305. They come complete, with valve covers, self aligning rockers and the works. I couldn't pass it up.
Anyhow, the intake is 1.84 and the exhaust 1.50. I have a 305 L69, what's the largest I could get these valves bumped up to? Also, should I have a 3 angle valve job done on these, and how much will it cost, and on average, what difference in HP will it make?
Thanks again.
