Thread: Trannyman, do you do Head work?

I'm just curious if you do. I'm looking to get some pricing. I was thinking about doing a set of heads and a cam. Not sure if i'll do it or not, cost of everything will determine that of course.

I know you did a hellova job on my S/C, so I figured for any port work i'd ask you first.

Thanks...

Hi Shawn, yes I do head porting also. The cost is $995 for a complete port job / head rebuild / valve job etc. Those that have my heads can speak of the quality and thoroughness of the port work, its done right. There generally a 3-4 week wait time on them as I usually lose a week of machine shop time plus fitting in porting time with everything else and it takes 10-20 hours to do both heads. This price does not include a core and is also with all stock valves and springs, upgrades are extra though I havent found any other valves I am happy with at this point so I prefer stock sizing unless you are going for every last few HP you can gather up. The 04+ L32 heads have the largest intake/exhaust valve combo and is a great core to start with.

Here are a few pics of some heads I am working on now. The exhaust ports are ported for the most port to what type of manifold/header combo you have. These are for pacesetter or Tog Extreme headers which have 1 3/4" primary tubes. Porting the exhaust port too much will hurt low end torque and also your header tube becomes a restriction so the large end of the port becomes a lazy airflow area. I have found over the year that keeping these sizes close to the exhaust helps out, keeping the outlet of the exhaust port smaller gives the airflow a lip to catch on for anti-reversion and helps with airflow velocity. Here are the pics......

I think Im going to barf. I want a machine shop and your skills. Those look really nice.

sure glad I didnt see those before going up to see you a few months ago.

cha ching!!!!!!! ***with a smile on my face***

Look at them Skills! do they see a flow bench?

I have never had them on a flow bench, there isnt one really close to me to use and it was never a concern. I have been porting for years and with these heads I learned what works well and what doesnt. Plus you cannot duplicate boost on a flowbench

Trannyman, are the L32 heads interchangeable with the L67's. Ive been looking for some heads for a project but if the L32's are better and I can use them, I'll look for a set of those instead.

Scotty the L32 heads bolt right on. And on a plus side other than starting with a slightly larger intake and exhaust valve they are newer and will have less mileage on them.

Ryan Im not sure about your heads. I have ported my share of SBC heads but the LT1 heads are a bit different and for the cost of porting and larger valves from me you would be better off buying reworked ones from a reputable supplier of them, or as I have recommended AFR all the way! If I ever have another small block that is the only head I will buy for it regardless the cost, trust me they are worth it!

The intake is no problem at all, but honestly if it was mine I would get an LT4 intake and call it a day

Appreciate the info Trannyman! I will definately keep you in mind.

I was thinking about doing heads and my LIM, match em all up. I already have 105# springs + ret on the shelf, along w/ Viton valve seals.

No problem, they are really the same as a L67 head with larger valves, and I have been preferring the use of those valves in the series 2 heads for longevity and easy adaptability.

Here are a few more pics of the heads, these are pics after they came back from the machine shop ready to assemble
