SBC Aluminum cylinder head recommendation!

Hello,


It's time for me to start upgrading my engine in my Camaro since I have the tranny and brakes all figured out. For starters this year I want to just upgrade the top end of the 355 that is currently in the car. Previous owner states its a 355 with forged internals and a hydraulic flat tappet cam. The current heads are 462 or 492 corvette heads that I will pull off and sell. I want to upgrade to a hydraulic roller and aluminum heads and a performer rpm manifold.

The car has a new TKO600 and 4:10 gears with a 26" tall tire. I want more power but maintain drivability. But I like drag racing too. My last two camaros ran 11.90's small block and 10.90's 540. So I like it to be fast.

I have used Dart Pro1's in the past on a 383 with a hydraulic roller around .535/.545 lift and that car ran great. I was hoping to try a different cylinder head this time.

What recommendations do you guys have for strong 355 with the potential of a bigger short block next year? Are RHS heads any good?

Thanks, Erik

RHS makes excellent castings.

I would contact Chad Speier at Speier Racing heads in Hays, KS....he has lots of different options that will be right up your alley.

Re: SBC Aluminum cylinder head recommendation!

Several options exist for decent 23* heads that would work on your combo. Some mentioned above. RHS, AFR, Dart, Brodix, AllPro, etc. any of these manufacturers have out of the box heads that will work fine for your stated goal.

As an example, 7-8 years ago my 3310 lb Camaro went 11.20's all day with a set of old iron Crane Fireball heads on a junker 408. Remember those old things? LOL. My point is, don't over think it, just get a head and valve train that will compliment your cam profile and performance objectives.

Have fun.

Re: SBC Aluminum cylinder head recommendation!

I like the sound of owning a set of AFR heads but I will look at all my options. I need to pick out cam as well. Like I said previously, I have used a Bullet camshaft before and the motor was pretty strong. I think the specs were something like 232/242 @ 050 and 535/545 lift, hydraulic roller. The car ran 11.90's in all stock trim and no traction bars or anything. I ned to start piecing the whole package together and see what I come up with.

Thanks for the replies,

Erik

Your car is looking amazing! I almost bought that car a few years ago before you bought it. I think it was from Indiana or Illinois when it was for sale, maybe western Ohio. Anyways, your doing a great job with it. Do you have any SBC parts for sale at all?

Thanks, Erik

My setup is with Brodix heads right out of the box, no porting etc. I could have spent $$ for head work, but why for a 99.9999999% street driven car?

Re: SBC Aluminum cylinder head recommendation!

You and me both, Al. My next street/strip engine will have some of Chad's heads and intake on it. Very impressive pump gas performance for a very fair price imo.

Re: SBC Aluminum cylinder head recommendation!

another head to consider is the TFS 200cc
202/160, with mild clean up they will make good power
a girly roller around 230s/240s with 1.6 rockers around 600 lift and good springs will make around 500hp

67RS502,

Girly cam huh? Can you suggest something more manly that is street friendly? I am looking for a package deal if possible.

Thanks, Erik

Re: SBC Aluminum cylinder head recommendation!

Erik: I have a set of AFR 195 heads on the ZZ430 clone I orignally built for my first '67 Camaro but is now going in to my '55 Bel Air, and with the GM Hot Cam it should be in the same 430hp/400ft.lbs range that GM had with their 430. However, CHP did a 383 build using the RHS 180 cc heads, with 64cc combustion chambers that put our really solid numbers, so I went with these heads for the 327 that I had rebuilt for my second '67 Camaro. I was very impressed with the quality of the machine work and preparation on the assembled RHS heads. If you can swing the AFR heads then I think both are a great improvement to a small block Chevy.

Relax, all right? My dad's a TV repairman, got an ultimate set of tools. I can fix it.
