For our 2 seater mk indy car, im building a nice pinto lump for it so thought id have a go at porting the head myself, its the first one ive done so be kind lol,











think i got a little excited on the inlets so their probably a tad to big but for our build im sure they'll be fine.

bit of an update for anyone who's interested, got the head back from the machine shop who blasted it, fitted the over size valves etc



larger valves


my porting skills

Fair play, at least you had the taters to try it yourself.

Fair play for trying it yourself, I wouldn't have the balls to do such a specialist job without any experience. Top marks

it may have paid you to have it flow tested, then if there was a mismatch on any of the ports you could have equalised them a little more.

Looks good though

For what im using it in i dont think it needs to be that perfect, but yes if it was a full blown competition engine i would agree.

Im going to have the engine set up with a guy who's good with carbs, then i may put it on the dyno, i would expect to see 150+ hopefully,

spec is

wiseco 92mm pistons
cossie rods
reground crank
lightend flywheel
whole bottom end balanced
h/p pump
new shells etc
head is ported
large single piece valves
stronger valve springs
kent cam
vernier pulley
fireblade carbs (40mm i think)

couple of pics of the bottom end
