There is nothing wrong with milling for more compression.  You are right, milling the block gets you more compression and better quench.  If you take a lot off the block, you still need to mill something to restore intake fit.  Probably better to mill the intake side of the heads and make the heads unique to that block.  If you mill the intake manifold, then want to change it for something else, the new one would need milled also.  If you have milled from the heads, any intake will still fit.


Hmmm very very good observation about mill the admission from the head! I will do this!

And what about rod push? Already heard about use some shorter... does it need some work or can i tune it by the screw?

Thanks alot!!

Here’s the link to the article that was published in the Y-Block Magazine that covered how to measure the cylinder heads to know how many thousandts would need to be cut off in order to reduce the combustion chamber volume 1 cc.

While there is some latitude in the pushrod adjuster to compensate for milling of the heads and/or deck, only during the engine assembly itself can you determine if a shorter pushrod is indeed required.
