Vanguard thin head gaskets from CPP?

Field6565 · 09-06-2015, 05:43 PM

I'm considering the gaskets but would it be better to just have the heads cut? If so, how much?
Thanks

I've been there. Mill the heads. What size heads?

Mill them .060" and use stock Graphoil gaskets.

what kind of improvement will we see after milling the heads?? I found a place locally that will do it for $75, Is it worth doing if the rest of the engine is stock?

It will increase the compression a bit. More compression is more power. Every little thing adds up.

Thanks Don. That's exactly what I needed to know. My cart is coming home from camp in a few weeks and I'm looking to do some mods.

What other mods have you done, or have planned?

Right now it has a dual valve springs, billet retainers, billet push rods and a advanced timing key. Governor has been removed. Planning on doing the 2bbl swap. Probably going with the 23hp cam. Maybe port the heads a bit since they will be removed for milling. I'm also planning on a better flowing exhaust. Do they sell flanges? If I was to do all these mods how much louder will it be?
