shawnt · 12-13-2009, 01:48 PM

Anyone here use a set of Racing Head Service bbc heads or have in the past? I am n on buying a set but don't know much about them. Thanks.

ripdog28 · 12-13-2009, 03:59 PM

I have seen a few companies that use them and build some stout motors. I have only heard good stuff about RHS.

shawnt · 12-13-2009, 05:13 PM

Thanks rip! I just keep seeing these ads everywhere and i didnt know whether they were legit or not. I'm thinking about getting a set for the big block because i don't wanna spend the extra money atm for brodix, dart, or afr. Still debating though.

Alex1 · 12-13-2009, 05:29 PM

RHS = CompCams

It's good stuff.

swb85 · 12-13-2009, 06:47 PM

Agreed....RHS makes great stuff. Pretty easy to squeeze 650hp out of a 454 with a set of their bbc heads.

shawnt · 12-14-2009, 03:38 AM

swb you just put a big SEG on my face. I likes the 650hp. Didn't know CompCams made RHS. I think i'll try a set but it's gonna be awhile. I come back from Iraq in late June so

. I just need something to make the ole pickup outrun my paw's camaro's. Doubt i can though. The 96 runs 6's in the 1/8 and the 79 runs low 7's. Maybe a little juice will get me there lol. Thanks for the help. Still open for more suggestions or advice.

**Captainfab** · 12-15-2009, 12:20 AM

Your sig says "Debating on building a 396" I would go with a 454 if you're wanting some go fast power. A 454 will make more torque which is what it takes to get a heavy truck moving. Top that with some RHS heads and as swb85 said, an easy 650hp.

Stay safe over there and thanks for your service

Hell, i have Dart heads (just as good or better) with a very tame cam and am pushing 500 ftlbs at about 3300 rpms.

shawnt · 12-15-2009, 03:12 AM

yeah, my sig does say "debating on building a 396" but i havent changed it in a while lol. i just bought a 454 not long ago and had my dad pick it up. and to you who said "thank you for your service" i say "thank you for your support"

djracer · 12-15-2009, 03:07 PM

Are the RHS heads aluminum? If not You might want to look at the patriots. My buddy has a pretty stout 489 with patriot aluminum heads. On a truck you really need to lose that weight off the nose.

Be safe and thanks again for what you do.

shawnt · 12-15-2009, 03:28 PM

Okay, i'll look around for some patriots also. I bought my wife a 50" TV, $1000 worth of clothes, and a necklace for christmas... all because i'll have something to hold against her when i get ready to build the 454

maybe she'll find it in her heart to let me go crazy but i doubt it

ulakovic22 · 12-17-2009, 03:59 PM

I have RHS heads on my BBC, but it hasn't started yet. Here are some real pics for you.

ulakovic22 · 12-17-2009, 04:02 PM

Here are some ported pics and flow numbers also because I like showing off

Hezie · 12-26-2009, 06:41 PM

I have a set on a 496.The engine I was coping made 625 and I can get about 10.5 mpg on a good day . Thank you for your service.

I would be interested to see the cam specs to compare to mine and see where I might end up.

Edit: As cast 320's?
