Default 331 stroker and injectors

ive been gone for awhile..
the machine shop has had my motor since march..
they are going to trade out the labor they did, for me to build them a website..

i told him i just wanted it to go fast.
so he came up with a set of aluminum 190cc chambered heads
and a 331 stroker kit from probe

ive got a trickflow intake, converted to maf, yada yada

You want to go fast, but those injectors and MAF are too much? It looks too cheap to me.

I'd go with the 30s. If you haven't bought the stroker kit, I'll save you some money there. What brand heads did he choose? Those look like Pro Comps. 190cc heads aren't common. If they are Pro Comps, get a new machinist because he's an idiot.

yeah i havent heard of any good head manufacuters with 190s. youve got to watch out for that cheap stuff thats all over ebay. i bought procomp head studs and one broke while i was tourqing it down. so then i had to pull the head back off, buy a new gasket and get the broken stud out of the block, of course it broke flush with the deck to make it fun to get out. but i would stay away from all of that.
