Nick @ Compuflow did the 915s you have. New SS valves 2.14I 1.81E, Bronze guides, Heads milled on face and matched on intake side so you just bolt your intake on, no milling of intake needed. Spring were set up for a comp cam hyd. 477 In 480 Ex. I am sure you could run up to a 509 lift purple shaft with these springs and be ok. also did a little bowl work with the oversized valves. Hope this helps.600$ plus shipping and that a hell of a set of heads for this price
