What a nice piece ,flow sheets show 28.5 % increase.My own measurement show 24.5% increase in exhaust ports and valves are 100 thousands larger with smaller shafts . My mehcanic was real pleased .They do make stock heads look like a toy.there being installed under my whipples as we speek on top of a monster cam and other good stuff hope to see 750 825 hp the old motors made 640 hp 7lbs boost no troubles 354 hrs old long blocks still in tact 150 compression on one 160 on the other

How much were the heads?

Got any moore info on your motor. What bore etc. I am running 750 HP on 5lbs boost bore is 30 over. I'm sure i would see at least 800hp with 7lbs boost. If you have any pics please post.

Don't leave us hangin, were always looking for new and fresh ideas for 496 power!!!

You said your shortblock is stock? How are your hypereutectic pistons holding up?

I didn't see a price for the port/polish and valve work on their website? Could you PM how much you paid for just the headwork? Thansk!

Me too on the CNC work, Thanks

Curious also about your short block. Could you maybe recap your setup i.e. crank, rods and pistons.
