And even though the badest heads on the market prolly wont let it breath like it needs to it is still worth a shot! And I bet you it will happen in the near future when someone comes along with enough money to foot the bill... but only time will tell.

Totally agree.

Healthy yes, no doubt but not max effort. 650-700 rwhp sounds real impressive-with a manual trans a little less impressive-with 500 cubes less impressive still.
At 12:1cr and using it as a street/strip motor yes a nice set set up and good power, probably good reliable power if tuned well on pump gas, even on 104.

Kumars heads were barely cleaned up, not ported IIRC

yes it is and you're right BUT, after a while you're gonna wanna rev it. If you're spending around 10k on a short block you should have room to grow. It's the nature of the racing beast. You're gonna want to step it up. You get this bottom end and until PROVEN otherwise you will have a well running reliable (only because it's hydraulic and N/A and not being pushed) set up. For 10k, that's a HUGE downside.
I keep hearing, yeah but he's running un ported stock heads and yeah but it's hydraulic and yeah but it makes great power down low. Guys-it's 10k. You can get a 481 Warkhawk sb for less than that and beat the **** out of it so why would you get this 500 over that?

This build is way down on power for hp/cid for using those cylinder heads. It probably has a lot to do with the cam choice but it still just doesn't add up. The torque is good. Those heads should be good for 800+hp with no problem on that size of an engine. Those heads will make 700hp on a 427cid like falling out of a tree.
