Our Stage I Heads, with our 98" piston/boring/complete Cometic gasket set, ring end gaps are set and installed on the pistons is only $1300.00.
Bolt it together and tune/ride/smile.

Turning into a build thread. Here are my first couple days stages down to the boxes then to the cylinders:





The only real notable tip I have is you will want the s shaped allen wrench for the right side throttle body bolts: http://www.homedepot.com/p/InSinkEra...N-00/100135761 they are a pain to reach and having more angles get to them in that tight space helps.

Here are the heads. They are going off to The King of Cubes in Des Moines to get pocket porting, cleaned up, and compression releases put in:

Why not just install a 120 racing motor? You've almost got that engine removed! lol

By the suggestions both on the thread and in my head I am also having the same shop bore the cylinders out to 3.975 to fit the pistons that djl suggested and targeting that 10.08/9.35:1 ratio. Will be taking the cylinders and pistons off this week.

Suggestion on packing the heads: put a piece of cardboard between the mouting surfaces and set them in the box that way with the chambers facing each other.

Better pack those better than that(heavier partition between the heads).........your may hear a call that you may not care for.
