These were originally on a low 10sec full weight 70GS,..I've profiled some of the quides a little more but still have a few more to do. Was going to run on my GSX but went with aluminum instead. Exhaust flange has been milled true, they are clean and crack free. I will finish what little is left to do for $350 or sell as is and you can finish for $200. They are obviously cut for big valves so there is substantial savings there vs starting from scratch,.they 1786's which have a smaller chamber from the start, they are ported and the heat passages are blocked. Shipping will be around $110 or I can deliver to the Nationals With the correct supporting hardware there is no reason why they wouldn't support 650hp imo
I doubt they'll get this far but I'll get inline. Seems the best deals pop up when I'm sleeping - dang time difference.
