So I went to the local boneyard last week and I found some GT40 heads on an explorer for $20. I pulled the heads and took them straight to the machine shop where a buddy of mine works/owns. I am going to have them magnafluxed, cleaned, valvejob, shaved and if possible do a little porting and polishing on them. I am going to be running a comp cams 35-302-8 cam and scorpion 1.6 RR. Now for the questions.

1) what is the Stock e7 combustion chamber in cc's?
2) what is the stock gt40 (f3xx casting) combustion chamber in cc's?
3) with the specs listed below on the cam will I have any clearance issues also using the roller rockers?

you are going to have to check PTV clearance.... I don't think you will have a problem... but do you really wanna bet your heads on a guess??
