Re: Going from procomp 210 heads to afr 210 how much more power?
Thanks every one for the help and info I really appreciate it.
I would pry be best to keep my heads and do the clean up on them.
jag327 what are you running for pistons to clear the procomp's isnt there problems with running domed with them?
my rotating is all balanced out to 8000 and I have 1/2 fuel line with a 130gph summit fuel pump so that's not holding me back. The car just run's lazy and guess that's what to expect with low compression and big cam. I have a boss hog torque converter I like it a lot after riding in my buddies car with the summit band one.
Here's my question. would I be better off shaving & cleaning up my heads then getting the compression to around 10.2 and a bit smaller cam OR keep my cam and clean the heads up and get some domed 11.5-13-1 compression pistons? I don't really want to run race fuel but if the car puts down better numbers with more compression and better fuel its worth it. I cant really afford to go 383 right now. eventually I would like to do a big block build or big block crate engine and then get the fancy headers and all that.

Thank about what you really like to do with the car more street or more race.
My Pops you to race back in the 50s 60s some in 70s he love 265/283/ But little 327 was he's motor 10s all day long. And had few 350s. A few big blocks
chevy's. I been through a lot of car and sold them. Right now have Belverdere 1967 440 high 9s, Mazda RX7 1984 with mopar 372 mid 9s, toyota celica gt 1984 with the R22 motor with 456 gear 11s
And now the 82 camaro with 327. low 11s
If you up the compression to 12.5 with the right cam, Do race port job on the heads match the intake ports to the heads, 850 holley,- should be getting in the 10s
When a motor is built up and I'm using a carb - I all ways jetting the carb for max mph if I'm racing.

check to see how much converter slip is in it too when you run next. Its a slightly overcammed setup with no compression so the trans and such may be ok, but you never know with converters. Keep playing with it.

They don't flow good for their volume but that is not as important as the fact they don't lock up until +.7 lift (no idea how high since the test was stopped at .7).
Calling a guy who builds head to spec for pro racers, like suggested before, is probably the best idea if you want more out of your heads. A port job specifically designed around your needs will beat any "out of box" wizardry and doesn't cost any more. You may also consider the intake manifold needing ported/replaced too.
I agree with Jag327, much more compression at least and a pro going over the heads if funds permit. Compression alone makes a huge difference on paper, I'm guessing it's happier with 11.5-12ish with that cam.
