How To CC Your Classic Volkswagen Heads. Bentley's Engine Part 5

CC’ing your heads is half of the equation to determining your compression ratio for your AirCooled Classic Volkswagen Beetle and other AirCooled engines. This is a simple process that only takes a few minutes.
These heads are from AA Performance, large valve heads with HD valve springs.

Another great video , thank you Gary

[@VWJawbreaker]

5150mxVW did I do a better job? 😂

[@mcdanielsmotorwerks423]

I was yelling at the video for you to install that plug! 🤪

[@VWJawbreaker]

Volkswagen Fetish I thought I had already lol 😂

That's so simple even I could screw it up!! Thanks for sharing!!

[@VWJawbreaker]

VeeDub P8 haha, you could easily do this! When are you going to get back on your projects? Miss seeing your updates.

great video, thank you.

Great explanation on this!! Nice!!!

Vintage Beetle And Memories thanks!

Those heads look like they have built in steps. When you cc's the heads with steps you need smaller plates to fit inside the step. The step is part of the cylinder,add to the deck height. I didn't know that either, until I read about in the thesamba.

[@VWJawbreaker]

Romeo I thought the same thing man, but I took an old cylinder without the piston installed and it fit where the step was.... if the step was removed it would make for less combustion chamber area.

[@vintage76vipergreenBeetle]

@@VWJawbreaker Sorry, I'm going to have to disagree with you. ✌

[@VWJawbreaker]

Romeo all good man, appreciate your feedback and comments as always 🤙

[@muzzcovw7674]

Not do disagree...but if you're measuring CCs to figure compression you MUST include the step area. Measuring inside the step will not give you an accurate compression calculation

[@RobStapleton]

Very cool!

[@VWJawbreaker]

Rob Stapleton thanks man.

+jonny5 I appreciate you checking it out. Stick around and make sure you comment and ask questions if you have any.

[@VWJawbreaker]

+jonny5 I’ve replied a few times but they aren’t posting.... Thanks for checking the videos out, stick around and comment with everyone.

[@MrTodo6969]

Do you need to do that for each side of the head or just one side and it’s good

[@VWJawbreaker]

It’s best to check every cylinder, do all 4 to ensure they’re all the same.

[@MrTodo6969]

@@VWJawbreaker I followed you’re video which are awesome by the way. My CCs are 50, 85.5 pistons, 69 bore displacement is 1585. Haven’t set my deck height yet and im wondering if I can set it at 8.1 for my compression ratio or should I choose a different compression ratio. Im in Ca and will use 87 or 89 octane gas.

[@VWJawbreaker]

@@MrTodo6969 compression ratio needs to be matched to the cam shaft. What cam are you running?

[@MrTodo6969]

@@VWJawbreaker oh boy, do I have to crack the case to determine that? I bought the bug used so I have no clue

[@VWJawbreaker]

@@MrTodo6969 you can usually see it behind the oil pump. If it’s a stock cam, I wouldn’t go 8.0, I’d keep it closer to 7.25-7.5 max.
