High compression heads?
 

I have a stock engine that I would like to put a new head on. I was going to go with the Snyder 6:1 head but now they are saying 6-8 weeks. What are your opinions on a Winfield, Lion Speed, or Thomas? My piston does not come above the block if this helps. In the future I may also run a single down draft.

I run an early Lion Head, It has power and no mechanical problems. I think the others you mentioned are good too. I prefer cast iron!

I run the 5.5:1 from Snyders and have been very pleased with the increased perfomance.

What sort of cranking pressure do you get with the 5.5 head.

Sorry, I can’t answer that question; however the increased performance was very apparent. Also I have put over 1500 miles on this head with no problems…just fun driving.:D

Just curious, what head gasket did you go with?

I used the gasket Snyders recommended for their head.

This is from Snyder's website:

"The 1932-34 model B version gasket is recommended with all 1932-34 stock heads as well as 1928-31 5.5:1 Snyder brand high compression head."

part number:B-6051-M

I torque the head to 55# and had to re-torque it several times after that. After it settled to 55# I torque to 60# and did it three times for it to finally settle in at 60#.
No sign of a leak anywhere and it is running great.

I also have a Snyder 5.5 head....almost 4 years old, about 5,500 miles on it. Very noticeable performance increase, especially with my heavier Town Sedan. If it is important to you, the Snyder heads looks totally stock, and lots of satisfied users out there. Works really well when coupled with the Mitchell overdrive!

I have been using Snyder's 5.5 heads on the three cars that I drive since the heads became available. At first, I was using the copper gaskets but have changed to the newer style as recommended by Snyder. The heads have been a great change, not just for power, but primarily for fuel economy. Don't ask how long the break even time will be!

I was using Brumfield's prior to the Snyder's heads and I was not able to keep the heads from warping and leaking.

I really like the looks of the Thomas head. I read that the cable won't screw into the dist., what do you do about this?

I'm a fan of the Thomas head, but mine has what appears to be a Brumfield profile. Runs great. The carbs need just little more tuning but I like the power that it puts out!

Just had to file down one of the fins for the pop out cable spring coil thing

On one of my cars, '31 SW TS, I'm running a Snyder's 5.5 milled .100 which probably gets it up to 6 to 1 or maybe a little higher. Works great. On this engine, like yours, the pistons don't protrude above the block - something to be aware of before milling. So, I'm saying, you don't have to wait for the Snyder's 6.0 head. BTW, I've used "B" head gaskets for many years. On this one I'm using the "modern" silicone impregnated "B" gasket. It's been a couple years and probably about 7,000 miles - no problem.

I have the snyder 5.5 head on two of my cars, a "model A speed head" on another, an original winfield 6-1 head on another, and a stock head on the last. The snyder head is good value, looks stock, and makes a big difference climbling hills. The "model A speed head is 6-1, and that really goes good.

Larry, that is a thought of milling the Snyder head .100. Has anyone else out there had luck milling the Snyder head?

Can you give us an evaluation of the Winfield head also, please?
