Alright got off the phone with Larry today my compression right now is around 13 to 1. He is going to send the right head gasket along with the intake and header gaskets. With the new gasket I'll be around 12.3 to 1. Larry is making everything right and I apperciate him fixing this. It will be awhile before I get this this fixed and running so bare with me. Once it's fixed I'll post the new numbers. Yes the motor is internally balanced for anyone who still wants to know. Thanks for the help Fraser I'll let you know how it turns out.

 

There is a head gasket to knock it down .7 of a point? WOW. You may want to check into that.

Just alittle update. Changed the headgaskets and while the heads were off I had a machine shop spec everything so I could figure out the compression With the fel pro's the compression ended up at 12.38 to 1. When it warms up I'll have Ed tune it again. Hopefully lowering the compression along with alot better gas and no miss will help me improve on the first dyno tune. First time I got 436.9 rwhp and 407. something rwtq. Graph looks real good til 4000 rpm or so and the miss kicks in. I also swapped the comp rockers with some crower which I heard are alot better rocker. Supposedly there been gains of 10+ at the wheels going from comp to crower. Any opinions on the rockers or improving the numbers?
