so phuck it no need for l series valves. im not to worried about it. well i went to go autoex the car today and turns out i broke both motor mounts on first run :(

i measured them before i put head on at a friend place. 30mm on exhaust 37mm on intake.

how much bigger are they ? This was a budget build, i have about 500 into it with everything. gasket kit, rings, lightening the flywheel, new chain/sprockets and tensioner, bike carbs, header.. so yeh it is night and day to my a12.. if i pull apart again i will do the valves.

I have a 89 toyota pickup here in the states. it has the 7.5 inch diff with 5 lug yes with drums. it came stock with 14s I have a rb20det in it actually. I put 410 gears in it and rear end seems pretty stout. the rear end housing will need to be narrowed I would think.

wow that's good im glad I got a good bargin then. to bad no more mt shasta would have loved to autox there. I will be going to a local autox this weekend to test out cars potential.

yeh seriously this motor has some good juice thanks to this head and cam!!

how much is a hea dlike this worth ?

thanks.

It obviously has oval ports but i tried figuring it out with no luck. i cc the cambers and it has 29cc. i remember measuring the exhaust valves at 30mm but intake was 35 or 37. I think. this must be a gx head or a nissan comp head?

Like i said on my first post i would show pictures of the head. I looked everywhere on the head and couldn't for the life of me find any casting numbers. I cc the camber and it was 29cc. here are 7 pictures below. also 2 more youtube videos of a incar
