[millow]

Helo guys im new to this site, im from the philippines and just got a 3sge 3rd gen for my st 171, was planing of upgrading the engine while its still out of the car, was thingking of puting itbs from a black top 4age and changing the values and springs from a beams which are allitle bit bigger or from a gte im still sourcing for the specs of other ge or gte and if they can be swap with minor machining, then go adjustable cam gears and cams with better lift, its kinda hard and expensive to look for 3sge parts here so im looking at the options from other gen that can be an upgrade for the 3rd gen, any sudgestions will be most appriciated. Thanks

thanks for the offer sir pasqual, i will seriuously consider that but i will have to save first, and like i said i am from the philippines there will be shipping costs, we have decent machine shops here that can do the head, how much did you shave off it, and what gasket did you use

as for now i will just prep the engine, will post pics
