So with Christmas just around the corner I wanted to use the opportunity to pick up some heads for my son's '73 project truck as a surprise. He's been working hard to pay for parts on his own to this point so a little bit of help from Dad isn't a bad thing this time.

The engine is the original rebuilt sbc 350 with the following mods:

- Comp Cams Xtreme Energy Cam & Lifter Kit (11/2010): Summit# CCA-K12-238-2; Cam/Lifter, Valvetrain(timing chain, sprockets, springs, valve stem seals, etc.), Hydraulic Flat Tappet, Advertised Duration 262int/270exh (Actual duration at 050” lift: 218/224), Lift .462int/.469exh. (Stock 350 SBC Cam Spec-estimated: dur @ .050 on that cam is 195/202)

- 1406 EB carb & Performer EPS manifold

- Full length headers, 2.25" exhaust with flowmaster mufflers

- 3.08 gearing

Basically I'm looking to increase low end torque and bump the hp a bit so I'd like to replace the stock heads with something but I just don't know what all of my options are so I'd like to get some direction from you guys. With a budget approach in mind (~$1000), should I get...

1. Rebuild 062 Vortec heads on ebay (~$175/head but I have to send back cores which I don't have so I'm not sure what the extra cost will be here)
2. Summit Vortec heads like this: https://www.summitracing.com/parts/sum-151124
3. Corvette Heads (which are best?)....err, just thinking out loud at this point
4. Another option that you would suggest?


I'd really like to utilize the components we currently have, options that don't require new intake, self aligning rockers, center bolt covers, etc (that the Vortecs require) so I'm definitely interested in hearing more on this point as it might help me keep the cost down and within budget. Hoping you guys can help me come up with a solution that I can put under the tree this year. Thanks for your help!
