I think everyone lost track about what is going on here.
We have one guy talking about BBC open chamber heads that cost about $1,650 bare and another person talking about BBC closed chamber head that costs about $2,100 bare or $2,900 depending on what angle they are.
When Pat runs his 14* or 18* heads he will run a different style pistons for those heads.
These heads let him use a piston with a smaller dome and still put him over 15 to 1 if that's where he wants to go.
The heads Pat has will put him at 1,000 hp or more naturally aspirated on a 565 engine.

johnny0, i do see your point about how if you see something wrong with another's engine combo, you correct them or give your personal opinion on how it should be. i do the exact same thing, thats why there clubhotrod. I every time i post a question about a situation or engine combo problem, i appreciate you guys helping me. but i built a few chevy engines with good power and have plently of experience. i know what works and what doesn't work on that particular engine. I have been down to many drag strips in minnesota and there are guys who have the most complicated and radical combinations, and there have been guys who told these guys that there engine combos will never work and it will be pos.those guys were the fastest down on the strip and also had half the money of many others in there cars.the reason why they were they fastest is because they what worked and were not afraid to race on the edge.these guys had simple mopars chevys and fords with iron heads with very little money into there eingines. theres been guys who come down there with expensive stroker engines and top of the line aluminum heads and got the living crap kicked out of them. the point is that sometimes one engine combo may seem strange or wrong to you, but they guy who's building it, might know a little more than you think he does. and even if the guys engine combo turns out like dog poo, then he learn from that combo and make it different.

I know of very few people who drag race that have very little money in their engine.
I am not sure what you mean by "having the living crap kicked out of them".
If you are talking about "bracket racing" which is racing against your "dial in" then I am really confused.
Then the only person some one kicked the living crap out of was themselves.
In bracket racing it is all about being consistent.
If there still is "heads up run", "run what you brung" racing in Minnesota well than that is different.

Boy, we sure have traveled far in this thread. Just to interject on the drag racing thing, I don't have much $$$ into my .030 over 396 and it makes a very reliable 13s bracket car. Here in CO we do have some heads up classes with generally 7 and 8s cars (at altitude) and everyone of those guys have more $$$$$ in their engine compartments than I have in my entire car (x3).

I wonder if al5570 found a good answer to his original question?

A 13 sec. bracket car???What class would that be???

I like to call it "super-slow" (Sportsman class). I'm shooting for mid 11's next year... BTW: bring this car to sea level, re-jet and I would already be low 12's

Why so much grief? I'm one of the faster cars in Sportsman class and sometimes run in the Pro Street class (<13.8s class break)... not to mention I'm one of very few there that is not a trailer-queen... you said yourself bracket racing is about consistentcy not speed...

So, Al5670, did we scare you away?? Sorry this went this way, it's easy to stray. How are you making out in your research??

sorry for the confusion, when i meant the guy got the living crap kicked out of him, i meant he got beat badly in the race. He was running his mouth and was saying he could beat this one guy with a 67' nova. the guy had very expensive 434 SBC, that was built to beat the guy with the nova. the guy with nova has very simple 468 with ported 781's and 6-71 blower with about 820hp. the 434 made more horsepower and torque per RPM than the blown 468. the guy with the nova track this guy down met him at the track and did several heads up races, the 468 nova won everytime.the nova has about $14,000 into the whole entire car. the 434 camaro had about $35,00-$40,000 into the car. it just shows brains over money!

yes he pulled all his hair out every time 1johnnyO and erik erikson are on you guys are trouble i have a hardtime with taking a120 or so cc open chamber head and cutting .080 off it and calling it and open chamber and the 45 on the intake valve would be on the deck that is not the way i would go you will have to sink the valves on the intake to get the 45 off the deck your back were you were? the point on my heads is they are small chamber and like erik said they can make good power on a 565 but i putting on my 650cid

Pat when I was talking about "rolling" heads I meant on small block after-market heads.
The Dart Pro 1 heads 345,AFR 357 etc I.M.O. are enough for most low deck BBC'S.
