have pics, have specs

head IS an 88270 head {EFI}

engine was running, broke ringland so a stock fresh 18RGU was put in instead.

has had port job on both intake and exhaust sides, has TRD valves on both inlet and exhaust, has HUGE cams, has been running on optimax, as u can see from the cleanliness of the intake port {the rumours about the optimax cleansing are true}, i have not touched the inlet ports, or tried to clean them in anyway

VALVES
Valves are TRD, inlet is 47mm{1.85"}, normally they are 45mm, exhaust are 40.5mm{1.6"} normally are 39mm

PORTS
Porting looks to be extensive, very high quality, {compare the std 88270 pic to the ported one, gave the exhaust port a bit of a run over with the fine wire "wheel" to get rid of some of the carbon, u can also see that its ported too.

CAMS
cams are a base grind,
Intake part number is 124E, {might be wade grinds} has a gross lift of 442"{11.42mm} net of 432' {10.97mm},
Exhaust part number is 166, has a gross lift of 475" {12.06mm} and 465" net {11.81mm}

gross std lift on 88270 cams are 10.3mm for the intake and 9.7 for the exhaust

pics below are of the ported head
