yates heads

[speed60]

I am looking for some advice on yates heads. I am thinking about upgrading but dont know much about it. Anyone know of a good person to talk to?

I personally like the sc1 heads the best, they produce great power and there torque curve is longer and smother. the c3s and d3s are good, but to me the sc1s are better on dirt. I bought a set from Penske racing a few years back and still run them on my open motor. you can go on line to there web site and get there ph number, they may still have some hope this helps.
