shaving a 3tc head for more compression = hp

[hemilove]

I would like to raise my compression on my hilux with a 3tc but how much is a good amount to shave off the head to get like 10:1 or 9.5:1 compression if yall have done this let me know bc these r1 carbs are pulling the air in but the engine cant keep up I want HP by just shaving the head and maybe a lil cam also

More Compression needs more octane, and yes a cam helps a lot with a set of proper valve springs for it, Shaving the head could be done all the way down till you touch the max shave button on the head, and u can go like .50 over that, but remember to measure valve to piston clearance and as long as you got .100 of clearance you are A-OK. again remember compression and low octane fuels dont mix!

choose a cam first and then let me know, a good safe cam will b a 284 AD by 476 lift or 494 lift, check Schneider cams as they have being very good to me and always accurate,
check the grind number 284F-HL

and then shave the head .50, then check the valve to piston for clearance and make sure is over .100 and add the single valve springs from ebay

and add the motorcycle carbs and you will be very happy man!

Carlos my friend had a rolla,the head was shaved , had header no cam just a carb out of an rx7 witch is 4 barrel you should see how that 3tc pulled and would start rite away even in winter,,, so I say head job and good Carb. & header is great for a cruiser

It is 50 out of a inch if you devide that inch in 1000 equal parts. so you got 950 of those left
