If you have to replace, upgrade!
we will see, money is tight and i plan on building a full engine to swap at a later date...im prob just going to get it running again and then upgrade a new head later

oh ya lol
ill replace the valves with stock for now (untill i do a full build later anyway)

just called a local machine shop that specializes in head work and they said that to remill the head for reinstalation is only 45$ and then 10$ to pressure wash the hole thing clean again...they also said that if i wanted to shave a lil off (to raise compression a bit ) that its no extra cost
i know somone on here has done this...anyone know what the same limits are for shaving the head??? .005?? i think is what someone did.
and since im replacing the head gasket anywhos....im goign to go with the thinner one....figure why not get some free ponies from increas c/r while im at it

(i do wan to be safe while doing it though...so any input is MORE then welcome!)

lol, i was talking about other parts, and ive got a local buddy thats got some spares thank you SOOOO much though!!!!!!
all i need to buy at this point is the bolts to replace the ones on holding on the head.
he has a full spare 2.2 that we can take parts from and a brand new head gasket....a local shop is going to shave the head for me and we are going to reassemble after that
talked with vince and he said ill be fine with the higher compression without tuning till him and i can meet..ill be taking it easy at first to make sure all is good, then when we tune ill go ***** out on the dyno then on the strip


(this is all as long as nothing on the bottom end of the engine is fucked)

current plans are to shave .020 off, if its too much we have a spare head to use, but from my research that *should* be safe, if it all works out then we will be reassembling starting a week from monday (will be out of town for a few days) and then HOPEFULLY she will live again..if not im seriously going to cry this time
and then bite the bullet and take it to a shop....
but with the engine torn down like this we should be able to make a decent assesment of what is going on.

with increased compression, i fully expect to see 180s to the wheels if not a bit more

let me know if you have any thoughts

lol, ill see if i can cancel my order with ced...as it is on back order and they havent processed, but i would LOVE a set of head bolts!! and do you have all 14 of them?? the e socket star ones and the 10 inner?


ya...all the exhaust valves are bent...
cyl looks ok, you can see where it impacted but because it was only as fast as the starter was turning it its ok...
and some more pics..




and this is where i get to work on the car lol
