starting another 6.0. it will be a no2 setup. what are the best heads for the job. ther are some harland sharp 1.7 on parts for sell are thes a good buy for the money? thanks

 

I went with AFR 205 (Mongoose) heads, knowing that I wanted to spray. Their studded and torqued, make 10.8:1 compression and flow real well. You maight find a used set over on Tech but they'll still be expensive, even used they go for $1500.00 easily.

You could try Richard at WCCH and see what they get for a ported and milled 317.

Is this a stock short block you're building on?
