| the cost on my labor with parts was only $3200 thats for everything....the interior surface is very smooth....I was looking in detail today actually...the pics don't show it that well....I tried to get the light in there but didn't have such luck. The valve train that went into these heads are made by Ferrea the valves are made of stainless steel.....the intake valves are 1mm oversized, the exhaust sides are stock size....the retainers are upgraded in titanium and the heads under went a 5 angle port and polish....the valves had to be back cut to ensure proper fitment....also the springs were dual coil for a stiffer spring rate.....the HP rating was set at different RPM settings and you can see at 12000rpms the heads flowed a considerable amount of air which calculated out to be somewhere near 70HP per cylinder...now obviously I am not reving to 12000rpms but I can rev to 7800 which at that point I gained 47ish HP per cylinder. Still doesn't say shop that did it tho :(
