Cam recommendation/valve spring compatibility Considering these heads for my T-Bucket with 355 and flat top pistons. Tight T400 trans and converter, 3:70 gears. What cam do you recommend and are the valve springs OK with it. I was considering a Comp Cams Extreme Energy 12-242-2. Looking for a nasty idle but good cruiser performance.

The valve springs on these heads will work fine with the camshaft you plan to use. That cam would be a good option for a stock or nearly stock torque converter stall speed.

No those rockers will not clear the valve springs on this cylinder head. You will need roller rocker arms such as 57533501 to clear the valve springs on these cylinder heads.

Intresting question, Not sure if this helps, but my 68 Chevelle's sbc came w/a crate 383 from unknown vendor, unknown cam specs, nor any documentation. (estate sale, ex-owner passed w/out leaving any history of 68 build) He installed lots of quality aftr-rmrkt. HP parts. Obviously knew what he was doing. The stroked 4-bolt main blck. has alumn. heads w/1.5 Scorpion "endurance" rlr. rckrs, ARP studs & guide-plates, hydralic lifters. The pushrods are non-adjustable after-market upgrade & motor runs strong w/no problems street or strip. Other than the possibility of block was decked during re-build necessitating custom sized pushrods. I'd venture to say your rlr.rckrs should fit perfectly as long as the initial valve lash is set correctly & rockrs. dont bind your valve springs @ hi-rpms, everything clears/ no parts touching(spin motor by hand, plugs out) overall valve-train geometry is spot-on. Unless youre completely aware on how to adjust valve lash correctly, I'd recommend a pro shop/engine-builder doing it, plus he may point out a possible problem you had no idea about..(don't ask me how I learned that one!! :) Good luck on your build, 383 sbc strokers are small blocks that think & run like they're a big-blocks!!!! Enjoy, Alan

These heads come fully assembled with 3/8" screw in studs and guide plates. You can not use self aligning rocker arms along with guide plates. It would be possible to remove the guide plates and use your self aligning rocker arms though. When removing the guide plates be sure to use a flat washer under the stud that is the same thickness as the guide plate to avoid possible damage to the heads and to keep the stud height correct.

As long as they're quality brand name, & rest of valve train matches(especially push-rod length being wihtin specs of eng.build) You can pick between several excellent brands such as: Crane, Comp..etc Personally, I always go w/Scorpion Racing: blue 1.5 "Endurance" full roller rocker (not just tip) Cause theyre tough & have a lifetime warranty regardless of what you do to the motor (although I wouldnt exactely admit to my Nitrous fueled/superchargd 12 second 1/4 mile week-end track addiction!!! :) Seriously, they rushed me a full brand new set when I sent them a pic of a couple of cracks on several rocker tips/no questions asked.... Be sure to register them should you go that route!! Enjoy, Alan

No these cylinder heads will not work well on a 305 engine. The bore size is too small on that engine for the size of valves and combustion chamber of this cylinder head. In many cases you would have to clearance the block in order to use these heads. This modification is something that only a machine shop should attempt. Even still the combustion chamber of these heads are 64cc and will lower your compression ratio as compared with the stock 58cc chamber of 305 heads.

Fel-Pro P1010 S/B Chevy 265-400 Copper Ring Head Gasket 4.166 In. Bore
(Part #3441010)
                        

These Fel-Pro gaskets work with both cast iron and aluminum heads. Pre-flattened steel wire ring gaskets have the strength of steel wire sealing with minimum brinelling of aluminum heads. Pre-flattened copper wire ring gaskets will not brinell aluminum heads. They offer superior heat dissipation. Multi-layer steel gaskets offer current leading-edge technology and provide a long-term, leakproof seal called Perma Torque MLS.

  • Gaskets are sold each
  • Pre-flattened copper wire
  • Nominal compression thickness: .039"
  • Compressed volume: 8.9 cc
  • Recommended for '86-'91 Corvette aluminum heads. Max 4.155" bore.
  • 4.166" bore gaskets can be used on 400 race engines with up to 4.155" max bore with minimal chamfer.
  • When using aluminum heads, we recommend gaskets with soft copper wire rings (such as 344-1010). This ensures that the aluminum head is not "scarred" by the combustion seal. Shim style 344-1094 will also work well with aluminum heads.
